+# Web Dashboards Overview
+
+The default port is 19999; for example, to access the dashboard on localhost, use: http://localhost:19999
+
+To view netdata collected data you access its **[REST API v1](api/)**.
+
+For our convenience, netdata provides 2 more layers:
+
+1. The `dashboard.js` javascript library that allows us to design custom dashboards using plain HTML. For information on creating custom dashboards, see **[Custom Dashboards](gui/custom/)** and **[Atlassian Confluence Dashboards](gui/confluence/)**
+
+2. Ready to be used web dashboards that render all the charts a netdata server maintains.
+
+## customizing the standard dashboards
+
+Charts information is stored at /usr/share/netdata/web/[dashboard_info.js](gui/dashboard_info.js). This file includes information that is rendered on the dashboard, controls chart colors, section and subsection heading, titles, etc.
+
+If you change that file, your changes will be overwritten when netdata is updated. You can preserve your settings by creating a new such file (there is /usr/share/netdata/web/[dashboard_info_custom.example.js](gui/dashboard_info_custom_example.js) you can use to start with).
+
+You have to copy the example file under a new name, so that it will not be overwritten with netdata updates.
+
+To configure your info file set in netdata.conf:
+
+```
+[web]
+ custom dashboard_info.js = your_file_name.js
+```

The right one is a **volume** calculation. Netdata calculated the total of the last 86.400 seconds (a day) which gives `kilobits`, then divided it by 8 to make it KB, then by 1024 to make it MB and then by 1024 to make it GB. Calculations like this are quite accurate, since for every value collected, every second, netdata interpolates it to second boundary using microsecond calculations.

+# Netdata Agent Web GUI
+
+## Generating dashboard.js
+
+The monolithic `dashboards.js` file is automatically generated by concatenating the source files located in the `web/gui/src/dashboard.js/` directory by running the build script:
+
+```sh
+cd web/gui
+make
+```
+
+After every change in the `src` directory, the `dashboard.js` file should be regenerated and commited to the repository.
+
+## Custom Dashboards
+
+For information on creating custom dashboards, see **[Custom Dashboards](custom/)** and **[Atlassian Confluence Dashboards](confluence/)**
+
+## Supported chart libraries
+
+- Dygraph
+- jQuery Sparkline
+- Peity
+- Google Charts
+- Morris
+- EasyPieChart
+- Gauge.js
+- D3
+- C3
+
+### Dygraph
+
+#### Settings
+
+[Example settings here](https://github.com/netdata/netdata/blob/e91f00d99f4965e985981b93fa46ef33f94dd726/web/dashboard.js#L3793)
+
+#### Value Range
+
+You can set the min and max values of the y-axis using `data-dygraph-valuerange="[MIN, MAX]"`
+
+### EasyPieChart
+
+#### Settings
+
+TBD
+
+#### Value Range
+
+You can set the max value of the chart using the following snippet:
+```html
+<div data-netdata="unique.id"
+ data-chart-library="easypiechart"
+ data-easypiechart-max-value="40"
+ ></div>
+```
+Be aware that values that exceed the max value will get expanded (e.g. "41" is still 100%). Similar for the minimum:
+```html
+<div data-netdata="unique.id"
+ data-chart-library="easypiechart"
+ data-easypiechart-min-value="20"
+ ></div>
+```
+If you specify both minimum and maximum, the rendering behavior changes. Instead of displaying the `value` based from zero, it is now based on the range that is provided by the snippet:
+```html
+<div data-netdata="unique.id"
+ data-chart-library="easypiechart"
+ data-easypiechart-min-value="20"
+ data-easypiechart-max-value="40"
+ ></div>
+```
+In the first example, a value of `30`, without specifying the minimum, fills the chart bar to `75%` (100% / 40 * 30). However, in this example the range is now `20` (40 - 20 = 20). The value `30` will fill the chart to **`50%`**, since it's in the middle between 20 and 40.
+
+This szenario is useful if you have metrics that change only within a specific range, e.g. temperatures that are very unlikely to fall out of range. In these cases it is more useful to have the chart render the values between the given min and max, to better highlight the changes within them.
+
+#### Negative Values
+
+EasyPieCharts can render negative values with the following flag:
+```html
+<div data-netdata="unique.id"
+ data-chart-library="easypiechart"
+ data-override-options="signed"
+ ></div>
+```
+Negative values are rendered counter-clockwise.
+
+#### Full example
+
+This is a chart that displays the hotwater temperature in the given range of 40 to 50.
+```html
+<div data-netdata="stiebeleltron_system.hotwater.hotwatertemp"
+ data-title="Hot Water Temperature"
+ data-decimal-digits="1"
+ data-chart-library="easypiechart"
+ data-colors="#FE3912"
+ data-width="55%"
+ data-height="50%"
+ data-points="1200"
+ data-after="-1200"
+ data-dimensions="actual"
+ data-units="°C"
+ data-easypiechart-max-value="50"
+ data-easypiechart-min-value="40"
+ data-common-max="netdata-hotwater-max"
+ data-common-min="netdata-hotwater-min"
+></div>
+```

+# Atlassian Confluence Dashboards
+
+With netdata you can build **live, interactive, monitoring dashboards** directly on Atlassian's **Confluence** pages.
+
+I see you already asking "why should I do this?"
+
+Well... think a bit of it.... confluence is the perfect place for something like that:
+
+1. All the employees of your company already have access to it.
+
+2. Most probably you have already several spaces on confluence, one for each project or service. Adding live monitoring information there is ideal: everything in one place. Your users will just click on the page and instantly the monitoring page they need will appear with only the information they need to know.
+
+3. You can create monitoring pages for very specific purposes, hiding all the information that is too detailed for most users, or explaining in detail things that are difficult for them to understand.
+
+So, what can we expect? What can netdata do on confluence?
+
+You will be surprised! **Everything a netdata dashboard does!**. Example:
+
+![final-confluence4](https://user-images.githubusercontent.com/2662304/34366214-767fa4b8-eaa1-11e7-83af-0b9b9b72aa73.gif)
+
+Let me show you how.
+
+> Let's assume we have 2 web servers we want to monitor. We will create a simple dashboard with key information about them, directly on confluence.
+
+### Before you begin
+
+Most likely your confluence is accessible via HTTPS. So, you need to proxy your netdata servers via an apache or nginx to make them HTTPS too. If your Confluence is HTTPS but your netdata are not, you will not be able to fetch the netdata content from the confluence page. The netdata wiki has many examples for proxying netdata through another web server.
+
+> So, make sure netdata and confluence can be accessed with the same protocol (**http**, or **https**).
+
+For our example, I will use these 2 servers:
+
+server|url
+----|----
+Server 1 | https://london.my-netdata.io
+Server 2 | https://frankfurt.my-netdata.io
+
+I will use the first server for the static dashboard javascript files.
+
+---
+
+Then, you need to enable the `html` plugin of confluence. We will add some plain html content on that page, and this plugin is required.
+
+### Create a new page
+
+Create a new confluence page and paste this into an `html` box:
+
+```html
+<script>
+// don't load bootstrap - confluence does not need this
+var netdataNoBootstrap = true;
+
+// select the web notifications to show on this dashboard
+// var netdataShowAlarms = true;
+// var netdataAlarmsRecipients = [ 'sysadmin', 'webmaster' ];
+</script>
+
+<script src="https://london.my-netdata.io/dashboard.js"></script>
+```
+
+like this (type `{html` for the html box to appear - you need the confluence html plugin enabled):
+
+![screenshot from 2017-12-25 00-46-20](https://user-images.githubusercontent.com/2662304/34329541-1dd9077c-e90d-11e7-988d-6820be31ff3f.png)
+
+### Add a few badges
+
+Then, go to your netdata and copy an alarm badge (the `<embed>` version of it):
+
+![copy-embed-badge](https://user-images.githubusercontent.com/2662304/34329562-dddea37e-e90d-11e7-9830-041a9f6a5984.gif)
+
+Then add another HTML box on the page, and paste it, like this:
+
+![screenshot from 2017-12-25 00-55-18](https://user-images.githubusercontent.com/2662304/34329569-4fc3d07c-e90e-11e7-8127-3127a21e1657.png)
+
+Hit **update** and you will get this:
+
+![screenshot from 2017-12-25 00-56-58](https://user-images.githubusercontent.com/2662304/34329573-8d4237cc-e90e-11e7-80bf-6c260456c690.png)
+
+This badge is now auto-refreshing. It will update itself based on the update frequency of the alarm.
+
+> Keep in mind you can add badges with custom netdata queries too. netdata automatically creates badges for all the alarms, but every chart, every dimension on every chart, can be used for a badge. And netdata badges are quite powerful! Check [Creating Badges](../../api/badges/) for more information on badges.
+
+So, let's create a table and add this badge for both our web servers:
+
+![screenshot from 2017-12-25 01-06-10](https://user-images.githubusercontent.com/2662304/34329609-d3e9ab00-e90f-11e7-99df-884196347538.png)
+
+Now we get this:
+
+![screenshot from 2017-12-25 01-07-10](https://user-images.githubusercontent.com/2662304/34329615-f7dea286-e90f-11e7-9b6f-600215494f96.png)
+
+### Add a netdata chart
+
+The simplest form of a chart is this (it adds the chart `web_log_nginx_netdata.response_statuses`, using 100% of the width, 150px height, and the last 10 minutes of data):
+
+```html
+<div
+ data-netdata="web_log_nginx_netdata.response_statuses"
+ data-width="100%"
+ data-height="150px"
+ data-before="0"
+ data-after="-600"
+></div>
+```
+
+Add this to `html` block on confluence:
+
+![screenshot from 2017-12-25 01-13-15](https://user-images.githubusercontent.com/2662304/34329635-cf83ab0a-e910-11e7-85a3-b72ccc2d54e4.png)
+
+And you will get this:
+
+![screenshot from 2017-12-25 01-14-09](https://user-images.githubusercontent.com/2662304/34329640-efd15574-e910-11e7-9004-94487dcde154.png)
+
+> This chart is **alive**, fully interactive. You can drag it, pan it, zoom it, etc like you do on netdata dashboards!
+
+Of course this too big. We need something smaller to add inside the table. Let's try this:
+
+```html
+<div
+ data-netdata="web_log_nginx_netdata.response_statuses"
+ data-legend="false"
+ data-dygraph-yaxislabelwidth="35"
+ data-dygraph-ypixelsperlabel="8"
+ data-after="-600"
+ data-before="0"
+ data-title=""
+ data-height="100px"
+ data-width="300px"
+></div>
+```
+
+The chart name is shown on all netdata charts, so just copy it from a netdata dashboard.
+
+We will fetch the same chart from both servers. To define the server we also added `data-host=` with the URL of each server, like this (we also added `<br/>` for a newline between the badge and the chart):
+
+![screenshot from 2017-12-25 01-25-05](https://user-images.githubusercontent.com/2662304/34329695-76fd2680-e912-11e7-9969-87f8d5b36145.png)
+
+Which gives us this:
+
+![screenshot from 2017-12-25 01-26-04](https://user-images.githubusercontent.com/2662304/34329700-989f0f2e-e912-11e7-8ac9-c78f82cfbdb0.png)
+
+Note the color difference. This is because netdata automatically hides dimensions that are just zero (the frankfurt server has only successful requests). To instruct netdata to disable this feature, we need to add another html fragment at the bottom of the page (make sure this is added after loading `dashboard.js`). So we edit the first block we added, and append a new `<script>` section to it:
+
+
+```html
+<script>
+// don't load bootstrap - confluence does not need this
+var netdataNoBootstrap = true;
+
+// select the web notifications to show on this dashboard
+// var netdataShowAlarms = true;
+// var netdataAlarmsRecipients = [ 'sysadmin', 'webmaster' ];
+</script>
+
+<script src="https://london.my-netdata.io/dashboard.js"></script>
+
+<script>
+// do not hide dimensions with just zeros
+NETDATA.options.current.eliminate_zero_dimensions = false;
+</script>
+```
+
+Now they match:
+
+![screenshot from 2017-12-25 01-30-14](https://user-images.githubusercontent.com/2662304/34329716-2ea83680-e913-11e7-847e-52b3f402aeb0.png)
+
+#### more options
+
+If you want to change the colors append `data-colors="#001122 #334455 #667788"`. The colors will be used for the dimensions top to bottom, as shown on a netdata dashboard. Keep in mind the default netdata dashboards hide by default all dimensions that are just zero, so enable them at the dashboard settings to see them all.
+
+You can get a percentage chart, by adding these on these charts:
+
+```html
+ data-append-options="percentage"
+ data-decimal-digits="0"
+ data-dygraph-valuerange="[0, 100]"
+ data-dygraph-includezero="true"
+ data-units="%"
+```
+
+The first line instructs netdata to calculate the percentage of each dimension, the second strips any fractional digits, the third instructs the charting library to size the chart from 0 to 100, the next one instructs it to include 0 in the chart and the last changes the units of the chart to `%`. This is how it will look:
+
+![screenshot from 2017-12-25 01-45-39](https://user-images.githubusercontent.com/2662304/34329774-570ef990-e915-11e7-899f-eee939564aaf.png)
+
+You can make any number of charts have common min and max on the y-range by adding `common-min="NAME"` and `common-max="NAME"`, where `NAME` is anything you like. Keep in mind for best results all the charts with the same `NAME` should be visible at once, otherwise a not-visible chart will influence the range and until it is updated the range will not adapt.
+
+### Add gauges
+
+Let's now add a few gauges. The chart we added has several dimensions: `success`, `error`, `redirect`, `bad` and `other`.
+
+Let's say we want to add 2 gauges:
+
+1. `success` and `redirect` together, in blue
+2. `error`, `bad` and `other` together, in orange
+
+We will add the following for each server. We have enclosed them in another a `<div>` because Confluence will wrap them if the page width is not enough to fit them. With that additional `<div>` they will always be next to each other.
+
+```html
+<div style="width: 300px; text-align: center;">
+<div
+ data-netdata="web_log_nginx_netdata.response_statuses"
+ data-host="https://london.my-netdata.io"
+ data-dimensions="success,redirect"
+ data-chart-library="gauge"
+ data-title="Good"
+ data-units="requests/s"
+ data-gauge-adjust="width"
+ data-width="120"
+ data-before="0"
+ data-after="-600"
+ data-points="600"
+ data-common-max="response_statuses"
+ data-colors="#007ec6"
+ data-decimal-digits="0"
+ ></div><div
+ data-netdata="web_log_nginx_netdata.response_statuses"
+ data-host="https://london.my-netdata.io"
+ data-dimensions="error,bad,other"
+ data-chart-library="gauge"
+ data-title="Bad"
+ data-units="requests/s"
+ data-gauge-adjust="width"
+ data-width="120"
+ data-before="0"
+ data-after="-600"
+ data-points="600"
+ data-common-max="response_statuses"
+ data-colors="#97CA00"
+ data-decimal-digits="0"
+ ></div>
+</div>
+```
+
+Adding the above will give you this:

+# Custom Dashboards
+
+You can:
+
+- create your own dashboards using simple HTML (no javascript is required for basic dashboards)
+- utilizing any or all of the available chart libraries, on the same dashboard
+- using data from one or more netdata servers, on the same dashboard
+- host your dashboard HTML page on any web server, anywhere
+
+netdata charts can also be added to existing web pages.
+
+Check this **[very simple working example of a custom dashboard](http://netdata.firehol.org/demo.html)**, and its **[html source](../demo.html)**.
+
+If you plan to put it on TV, check **[tv.html](../tv.html)**. This is a screenshot of it, monitoring 2 servers on the same page:
+
+![image](https://cloud.githubusercontent.com/assets/2662304/14252187/d8d5f78e-fa8e-11e5-990d-99821d38c874.png)
+--
+
+## Web directory
+
+The default web root directory is `/usr/share/netdata/web` where you will find examples such as tv.html, and demo.html as well as the main dashboard contained in index.html.
+Note: index.html have a different syntax. Don't use it as a template for simple custom dashboards.
+
+## Example empty dashboard
+
+If you need to create a new dashboard on an empty page, we suggest the following header:
+
+```html
+<!DOCTYPE html>
+<html lang="en">
+<head>
+ <title>Your dashboard</title>
+
+ <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
+ <meta charset="utf-8">
+ <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
+ <meta name="viewport" content="width=device-width, initial-scale=1">
+ <meta name="apple-mobile-web-app-capable" content="yes">
+ <meta name="apple-mobile-web-app-status-bar-style" content="black-translucent">
+
+ <!-- here we will add dashboard.js -->
+
+</head>
+<body>
+
+<!-- here we will add charts -->
+
+</body>
+</html>
+```
+
+
+## dashboard.js
+
+To add netdata charts to any web page (dedicated to netdata or not), you need to include the `/dashboard.js` file of a netdata server.
+
+For example, if your netdata server listens at `http://box:19999/`, you will need to add the following to the `head` section of your web page:
+
+```html
+<script type="text/javascript" src="http://box:19999/dashboard.js"></script>
+```
+
+### what dashboard.js does?
+
+`dashboard.js` will automatically load the following:
+
+1. `dashboard.css`, required for the netdata charts
+
+2. `jquery.min.js`, (only if jquery is not already loaded for this web page)
+
+3. `bootstrap.min.js` (only if bootstrap is not already loaded) and `bootstrap.min.css`.
+
+ You can disable this by adding the following before loading `dashboard.js`:
+
+```html
+<script>var netdataNoBootstrap = true;</script>
+```
+
+4. `jquery.nanoscroller.min.js`, required for the scrollbar of the chart legends.
+
+5. `bootstrap-toggle.min.js` and `bootstrap-toggle.min.css`, required for the settings toggle buttons.
+
+6. `font-awesome.min.css`, for icons.
+
+When `dashboard.js` loads will scan the page for elements that define charts (see below) and immediately start refreshing them. Keep in mind more javascript modules may be loaded (every chart library is a different javascript file, that is loaded on first use).
+
+### Prevent dashboard.js from starting chart refreshes
+
+If your web page is not static and you plan to add charts using javascript, you can tell `dashboard.js` not to start processing charts immediately after loaded, by adding this fragment before loading it:
+
+```html
+<script>var netdataDontStart = true;</script>
+```
+
+The above, will inform the `dashboard.js` to load everything, but not process the web page until you tell it to.
+You can tell it to start processing the page, by running this javascript code:
+
+```js
+NETDATA.start();
+```
+
+Be careful not to call the `NETDATA.start()` multiple times. Each call to this function will spawn a new thread that will start refreshing the charts.
+
+If, after calling `NETDATA.start()` you need to update the page (or even get your javascript code synchronized with `dashboard.js`), you can call (after you loaded `dashboard.js`):
+
+```js
+NETDATA.pause(function() {
+ // ok, it is paused
+
+ // update the DOM as you wish
+
+ // and then call this to let the charts refresh:
+ NETDATA.unpause();
+});
+```
+
+### The default netdata server
+
+`dashboard.js` will attempt to auto-detect the URL of the netdata server it is loaded from, and set this server as the default netdata server for all charts.
+
+If you need to set any other URL as the default netdata server for all charts that do not specify a netdata server, add this before loading `dashboard.js`:
+
+```html
+<script type="text/javascript">var netdataServer = "http://your.netdata.server:19999";</script>
+```
+
+---
+
+# Adding charts
+
+To add charts, you need to add a `div` for each of them. Each of these `div` elements accept a few `data-` attributes:
+
+### The chart unique ID
+
+The unique ID of a chart is shown at the title of the chart of the default netdata dashboard. You can also find all the charts available at your netdata server with this URL: `http://your.netdata.server:19999/api/v1/charts` ([example](http://netdata.firehol.org/api/v1/charts)).
+
+To specify the unique id, use this:
+
+```html
+<div data-netdata="unique.id"></div>
+```
+
+The above is enough for adding a chart. It most probably have the wrong visual settings though. Keep reading...
+
+### The duration of the chart
+
+You can specify the duration of the chart (how much time of data it will show) using:
+
+```html
+<div data-netdata="unique.id"
+ data-after="AFTER_SECONDS"
+ data-before="BEFORE_SECONDS"
+ ></div>
+```
+
+`AFTER_SECONDS` and `BEFORE_SECONDS` are numbers representing a time-frame in seconds.
+
+The can be either:
+
+- **absolute** unix timestamps (in javascript terms, they are `new Date().getTime() / 1000`. Using absolute timestamps you can have a chart showing always the same time-frame.
+
+- **relative** number of seconds to now. To show the last 10 minutes of data, `AFTER_SECONDS` must be `-600` (relative to now) and `BEFORE_SECONDS` must be `0` (meaning: now). If you want the chart to auto-refresh the current values, you need to specify **relative** values.
+
+### Chart sizes
+
+You can set the size of the chart using this:
+
+```html
+<div data-netdata="unique.id"
+ data-width="WIDTH"
+ data-height="HEIGHT"
+ ></div>
+```
+
+`WIDTH` and `HEIGHT` can be anything CSS accepts for width and height (e.g. percentages, pixels, etc).
+Keep in mind that for certain chart libraries, `dashboard.js` may apply an aspect ratio to these.
+
+If you want `dashboard.js` to remember permanently (browser local storage) the dimensions of the chart (the user may resize it), you can add: `data-id="SETTINGS_ID"`, where `SETTINGS_ID` is anything that will be common for this chart across user sessions.
+
+### Netdata server
+
+Each chart can get data from a different netdata server. You can give per chart the netdata server using:
+
+```html
+<div data-netdata="unique.id"
+ data-host="http://another.netdata.server:19999/"
+ ></div>
+```
+
+If you have ephemeral monitoring setup ([More info here](../../../streaming/#monitoring-ephemeral-nodes)) and have no direct access to the nodes dashboards, you can use the following:
+
+```html
+<div data-netdata="unique.id"
+ data-host="http://yournetdata.server:19999/host/reported-hostname"
+ ></div>
+```
+### Chart library
+
+The default chart library is `dygraph`. You set a different chart library per chart using this:
+
+```html
+<div data-netdata="unique.id"
+ data-chart-library="gauge"
+ ></div>
+```
+
+Each chart library may support more chart-library specific settings. Please refer to the documentation of the chart library you are interested, in this wiki or the source code:
+
+- options `data-dygraph-XXX` [here](https://github.com/netdata/netdata/blob/643cfe20a8d8beba0ed31ec6afaade80853fd310/web/dashboard.js#L6251-L6361)
+- options `data-easypiechart-XXX` [here](https://github.com/netdata/netdata/blob/643cfe20a8d8beba0ed31ec6afaade80853fd310/web/dashboard.js#L7954-L7966)
+- options `data-gauge-XXX` [here](https://github.com/netdata/netdata/blob/643cfe20a8d8beba0ed31ec6afaade80853fd310/web/dashboard.js#L8182-L8189)

+- options `data-sparkline-XXX` [here](https://github.com/netdata/netdata/blob/643cfe20a8d8beba0ed31ec6afaade80853fd310/web/dashboard.js#L5940-L5985)
+- options `data-peity-XXX` [here](https://github.com/netdata/netdata/blob/643cfe20a8d8beba0ed31ec6afaade80853fd310/web/dashboard.js#L5892)
+
+
+### Data points
+
+For the time-frame requested, `dashboard.js` will use the chart dimensions and the settings of the chart library to find out how many data points it can show.
+
+For example, most line chart libraries are using 3 pixels per data point. If the chart shows 10 minutes of data (600 seconds), its update frequency is 1 second, and the chart width is 1800 pixels, then `dashboard.js` will request from the netdata server: 10 minutes of data, represented in 600 points, and the chart will be refreshed per second. If the user resizes the window so that the chart becomes 600 pixels wide, then `dashboard.js` will request the same 10 minutes of data, represented in 200 points and the chart will be refreshed once every 3 seconds.
+
+If you need to have a fixed number of points in the data source retrieved from the netdata server, you can set:
+
+```html
+<div data-netdata="unique.id"
+ data-points="DATA_POINTS"
+ ></div>
+```
+
+Where `DATA_POINTS` is the number of points you need.
+
+You can also overwrite the pixels-per-point per chart using this:
+
+```html
+<div data-netdata="unique.id"
+ data-pixels-per-point="PIXELS_PER_POINT"
+ ></div>
+```
+
+Where `PIXELS_PER_POINT` is the number of pixels each data point should occupy.
+
+### Data grouping method
+
+Netdata supports **average** (the default), **sum** and **max** grouping methods. The grouping method is used when the netdata server is requested to return fewer points for a time-frame, compared to the number of points available.
+
+You can give it per chart, using:
+
+```html
+<div data-netdata="unique.id"
+ data-method="max"
+ ></div>
+```
+
+### Changing rates
+
+Netdata can change the rate of charts on the fly. So a charts that shows values **per second** can be turned to **per minute** (or any other, e.g. **per 10 seconds**), with this:
+
+```html
+<div data-netdata="unique.id"
+ data-method="average"
+ data-gtime="60"
+ data-units="per minute"
+ ></div>
+```
+
+The above will provide the average rate per minute (60 seconds).
+Use 60 for `/minute`, 3600 for `/hour`, 86400 for `/day` (provided you have that many data).
+
+- The `data-gtime` setting does not change the units of the chart. You have to change them yourself with `data-units`.
+- This works only for `data-method="average"`.
+- netdata may aggregate multiple points to satisfy the `data-points` setting. For example, you request `per minute` but the requested number of points to be returned are not enough to report every single minute. In this case netdata will sum the `per second` raw data of the database to find the `per minute` for every single minute and then **average** them to find the **average per minute rate of every X minutes**. So, it works as if the data collection frequency was per minute.
+
+### Selecting dimensions
+
+By default, `dashboard.js` will show all the dimensions of the chart.
+You can select specific dimensions using this:
+
+```html
+<div data-netdata="unique.id"
+ data-dimensions="dimension1,dimension2,dimension3,..."
+ ></div>
+```
+
+netdata supports coma (` , `) or pipe (` | `) separated [simple patterns](../../../libnetdata/simple_pattern/) for dimensions. By default it searches for both dimension IDs and dimension NAMEs. You can control the target of the match with: `data-append-options="match-ids"` or `data-append-options="match-names"`. Spaces in `data-dimensions=""` are matched in the dimension names and IDs.
+
+### Chart title
+
+You can overwrite the title of the chart using this:
+
+```html
+<div data-netdata="unique.id"
+ data-title="my super chart"
+ ></div>
+```
+
+### Chart units
+
+You can overwrite the units of measurement of the dimensions of the chart, using this:
+
+```html
+<div data-netdata="unique.id"
+ data-units="words/second"
+ ></div>
+```
+
+### Chart colors
+
+`dashboard.js` has an internal palette of colors for the dimensions of the charts.
+You can prepend colors to it (so that your will be used first) using this:
+
+```html
+<div data-netdata="unique.id"
+ data-colors="#AABBCC #DDEEFF ..."
+ ></div>
+```
+
+### Extracting dimension values
+
+`dashboard.js` can update the selected values of the chart at elements you specify. For example, let's assume we have a chart that measures the bandwidth of eth0, with 2 dimensions `in` and `out`. You can use this:
+
+```html
+<div data-netdata="net.eth0"
+ data-show-value-of-in-at="eth0_in_value"
+ data-show-value-of-out-at="eth0_out_value"
+ ></div>
+
+My eth0 interface, is receiving <span id="eth0_in_value"></span>
+and transmitting <span id="eth0_out_value"></span>.
+```
+
+### Hiding the legend of a chart
+
+On charts that by default have a legend managed by `dashboard.js` you can remove it, using this:
+
+```html
+<div data-netdata="unique.id"
+ data-legend="no"
+ ></div>
+```
+
+### API options
+
+You can append netdata **[[REST API v1]]** data options, using this:
+
+```html
+<div data-netdata="unique.id"
+ data-append-options="absolute,percentage"
+ ></div>
+```
+
+A few useful options are:
+
+- `absolute` to show all values are absolute (i.e. turn negative dimensions to positive)
+- `percentage` to express the values as a percentage of the chart total (so, the values of the dimensions are added, and the sum of them if expressed as a percentage of the sum of all dimensions)
+- `unaligned` to prevent netdata from aligning the charts (e.g. when requesting 60 seconds aggregation per point, netdata returns chart data aligned to XX:XX:00 to XX:XX:59 - similarly for hours, days, etc - the `unaligned` option disables this feature)
+- `match-ids` or `match-names` is used to control what `data-dimensions=` will match.
+
+### Chart library performance
+
+`dashboard.js` measures the performance of the chart library when it renders the charts. You can specify an element ID you want this information to be visualized, using this:
+
+```html
+<div data-netdata="unique.id"
+ data-dt-element-name="measurement1"
+ ></div>
+
+refreshed in <span id="measurement1"></span> milliseconds!
+```
+
+### Syncing charts y-range
+
+If you give the same `data-common-max="NAME"` to 2+ charts, then all of them will share the same max value of their y-range. If one spikes, all of them will be aligned to have the same scale. This is done for the cpu interrupts and and cpu softnet charts at the dashboard and also for the `gauge` and `easypiecharts` of the netdata home page.
+
+```html
+<div data-netdata="chart1"
+ data-common-max="chart-group-1"
+ ></div>
+
+<div data-netdata="chart2"
+ data-common-max="chart-group-1"
+ ></div>
+```
+
+The same functionality exists for `data-common-min`.
+
+### Syncing chart units
+
+netdata dashboards support auto-scaling of units. So, `MB` can become `KB`, `GB`, etc dynamically, based on the value to be shown.
+
+Giving the same `NAME` with `data-common-units="NAME"`, 2+ charts can be forced to always have the same units.
+
+```html
+<div data-netdata="chart1"
+ data-common-units="chart-group-1"
+ ></div>
+
+<div data-netdata="chart2"
+ data-common-units="chart-group-1"
+ ></div>
+```
+
+### Setting desired units
+
+Charts can be scaled to specific units with `data-desired-units="UNITS"`. If the dashboard can convert the units to the desired one, it will do.
+
+```html
+<div data-netdata="chart1"
+ data-desired-units="GB"
+ ></div>
+```
