-# Chart dimensions, contexts, and families
-
-While Netdata's charts require no configuration and are [easy to interact with](https://github.com/netdata/netdata/blob/master/docs/dashboard/interact-charts.mdx),
-they have a lot of underlying complexity. To meaningfully organize charts out of the box based on what's happening in
-your nodes, Netdata uses the concepts of **dimensions**, **contexts**, and **families**. 
-
-Understanding how these work will help you more easily navigate the dashboard, [write new
-alarms](https://github.com/netdata/netdata/blob/master/docs/monitor/configure-alarms.md), or play around with the [API](https://github.com/netdata/netdata/blob/master/web/api/README.md).
-
-For a refresher on the anatomy of a chart, see [dashboards and charts](https://github.com/netdata/netdata/blob/master/docs/dashboard/how-dashboard-works.mdx).
-
-## Dimension
-
-A **dimension** is a value that gets shown on a chart. The value can be raw data or calculated values, such as the
-average (the default), minimum, or maximum. These values can then be given any type of unit. For example, CPU
-utilization is represented as a percentage, disk I/O as `MiB/s`, and available RAM as an absolute value in `MiB` or
-`GiB`.
-
-Beneath every chart (or on the right-side if you configure the dashboard) is a legend of dimensions. When there are
-multiple dimensions, you'll see a different entry in the legend for each dimension.
-
-The **Apps CPU Time** chart (with the [context](#context) `apps.cpu`), which visualizes CPU utilization of
-different types of processes/services/applications on your node, always provides a vibrant example of a chart with
-multiple dimensions.
-

-dimensions](https://user-images.githubusercontent.com/1153921/114207816-a5cb7400-9911-11eb-8800-06f60b745f9c.png)
-
-The chart shows 13 unique dimensions, such as `httpd` for the CPU utilization for web servers, `kernel` for anything
-related to the Linux kernel, and so on. In your dashboard, these specific dimensions will almost certainly be different.
-
-Dimensions can be [hidden](https://github.com/netdata/netdata/blob/master/docs/dashboard/interact-charts.mdx#show-and-hide-dimensions) to help you focus your
-attention.
-
-## Context
-
-A **context** is a way of grouping charts by the types of metrics collected and dimensions displayed. It's kind of like
-a machine-readable naming and organization scheme.
-
-For example, the **Apps CPU Time** has the context `apps.cpu`. A little further down on the dashboard is a similar
-chart, **Apps Real Memory (w/o shared)** with the context `apps.mem`. The `apps` portion of the context is the **type**,
-whereas anything after the `.` is specified either by the chart's developer or by the [**family**](#family). 
-
-By default, a chart's type affects where it fits in the menu, while its family creates submenus.
-
-Netdata also relies on contexts for [alarm configuration](https://github.com/netdata/netdata/blob/master/docs/monitor/configure-alarms.md) (the [`on`
-line](https://github.com/netdata/netdata/blob/master/health/REFERENCE.md#alarm-line-on)).
-
-## Family
-
-**Families** are a _single instance_ of a hardware or software resource that needs to be displayed separately from
-similar instances.
-
-For example, let's look at the **Disks** section, which contains a number of charts with contexts like `disk.io`,
-`disk.ops`, `disk.backlog`, and `disk.util`.  If your node has multiple disk drives at `sda` and `sdb`, Netdata creates
-a separate family for each.
-
-Netdata now merges the contexts and families to create charts that are grouped by family, following a
-`[context].[family]` naming scheme, so that you can see the `disk.io` and `disk.ops` charts for `sda` right next to each
-other.
-
-Given the four example contexts, and two families of `sda` and `sdb`, Netdata will create the following charts and their
-names:
-
-| Context        | `sda` family       | `sdb` family       |
-| :------------- | ------------------ | ------------------ |
-| `disk.io`      | `disk_io.sda`      | `disk_io.sdb`      |
-| `disk.ops`     | `disk_ops.sda`     | `disk_ops.sdb`     |
-| `disk.backlog` | `disk_backlog.sda` | `disk_backlog.sdb` |
-| `disk.util`    | `disk_util.sda`    | `disk_util.sdb`    |
-
-## What's next?
-
-With an understanding of a chart's dimensions, context, and family, you're now ready to dig even deeper into Netdata's
-dashboard. We recommend looking into [using the timeframe selector](https://github.com/netdata/netdata/blob/master/docs/dashboard/visualization-date-and-time-controls.mdx).
-
-If you feel comfortable with the [dashboard](https://github.com/netdata/netdata/blob/master/docs/dashboard/how-dashboard-works.mdx) and interacting with charts, we
-recommend learning about [configuration](https://github.com/netdata/netdata/blob/master/docs/configure/nodes.md). While Netdata doesn't _require_ a complicated setup
-process or a query language to create charts, there are a lot of ways to tweak the experience to match your needs.
