It focuses on two different aspects of visualization programming: **basic charts** for creating historical reports, and **real-time charts** for displaying frequently updating timeseries data. + +To get started using Epoch, please refer to the [Epoch Project Site](http://epochjs.github.io/epoch/). There you can find full documentation and guides to help you start using Epoch right away. + +### Installation +Epoch can be easily installed via the following package managers: + +* [npm](https://www.npmjs.com/package/epoch-charting) +* [bower](http://bower.io/search/?q=epoch) +* [packagist](https://packagist.org/packages/epochjs/epoch) + +If you don't see your favorite package manager in the list above feel free to +[open up an issue](https://github.com/epochjs/epoch/issues/new) and let us know. +Finally, you can download any release of the library from the +[project releases page](https://github.com/epochjs/epoch/releases). + +**Important:** Epoch requires [d3](https://github.com/mbostock/d3). In order to +work properly your page must load d3 before epoch. + +#### Public CDN URLs +If you don't want to host the files yourself, you can use +[jsDelivr](http://www.jsdelivr.com/) to serve the files: + +1. Visit [epoch page on jsDelvr](http://www.jsdelivr.com/projects/epoch). +2. Copy the provided URL's and link to them in your project. + +### Developing Epoch + +Developing Epoch is a reasonably straight forward process. In this section we'll +cover the basic on how to develop Epoch by detailing common build task, exploring +how the source is arranged, and finally show how to use rendering tests to aid +development. + +#### Configuring Development Environment + +Epoch requires the following for development: + +1. [Node.js](https://nodejs.org/en/) (v4.1.1+) +2. [NPM](https://www.npmjs.com/) (v2.1.0+) + +Once both are installed on your machine you will need to run `npm install` from +the repository's root directory in order to install the npm packages required +to develop epoch. + +Once you have installed the required npm packages you can use `gulp build` to +fully rebuild the source (see more information about gulp tasks below). + + +#### Basic Development Process + +The best way to start contributing to Epoch is to follow these steps: + +1. Change to the source directory for the project +2. Run `gulp watch` to recompile the project after source files change +3. Make changes in a source file (either in `src/` or `sass/`) +4. In a web browser open the `test/index.html` and browse the rendering tests +5. Use the rendering tests to see if your changes had the desired result +6. Ensure unit tests with pass `npm test` + +#### Testing + +Epoch uses two types of testing to ensure that changes do not cause unintended +side effects. The first, unit tests, ensure that the core functional components +of the library work as expected. The second, rendering tests, allow you to +ensure that charts and graphs are correctly rendered. + +It is important to keep both unit test and rendering tests up-to-date! When +developing, use the following guidelines: + +* When adding new features make sure to add new tests +* When changing existing functionality, ensure that the appropriate both types + of tests still pass +* If you want to make a new type of chart, add a whole new test suite for that + chart! + +Keeping the tests current makes it easier for others to review your code and +spot issues. Also, pull requests without appropriate testing will not be +merged. + + +#### Gulp Tasks + +Epoch uses [gulp](https://github.com/gulpjs/gulp) to perform various tasks. The +`gulpfile.js` file defines the following tasks: + +* `gulp clean` - Cleans the `dist/` directory. +* `gulp build` - Builds the CoffeeScript and Sass source into the `dist/` + directory. +* `gulp watch` - Starts a watch script to recompile CoffeeScript and Sass when + any files change. + +#### Source Structure + +The directory structure for the Epoch project follows some basic guidelines, here's an overview of how it is structured: + +``` +dist/ - Compiled JavaScript and CSS source +src/ - Main source directory + core/ - Core Epoch Library Files + util.coffee - Library Utility Routines + d3.coffee - d3 Extensions + format.coffee - Data formatters + chart.coffee - Base Chart Classes + css.coffee - CSS Querying Engine + adapters/ - 3rd Party Library Adapters (currently only jQuery) + basic/ - Basic Chart Classes + time/ - Real-time Chart Classes + adapters.coffee - Options / Global Classes for Adapter Implementations + basic.coffee - Base Classes for Basic Charts + data.coffee - Data Formatting + epoch.coffee - Main source file, defines name spaces, etc. + model.coffee - Data Model + time.coffee - Base Classes for Real-Time Charts +sass/ - Scss source for the default epoch stylesheet +tests/ + render/ - Rendering tests + basic/ - Basic chart rendering tests + real-time/ - Real-time rendering tests + unit/ - Unit tests +``` + +### Release Checklist + +- Run `npm test` and ensure all tests pass +- Run `npm version [major|minor|patch]` +- Run `npm publish` +- Update CHANGELOG.md with the changes since last release +- Update the `gh-pages` branch's library version in `_config.yml` diff --git a/debian/missing-sources/epoch/bower.json b/debian/missing-sources/epoch/bower.json new file mode 100644 index 0000000..36ee8e6 --- /dev/null +++ b/debian/missing-sources/epoch/bower.json @@ -0,0 +1,37 @@ +{ + "name": "epoch", + "description": "A general purpose, real-time visualization library.", + "main": [ + "dist/js/epoch.min.js", + "dist/css/epoch.min.css" + ], + "license": "MIT", + "ignore": [ + "**/.*", + "/src", + "/sass", + "/tests", + "/Cakefile", + "/CHANGELOG.md", + "/package.json" + ], + "authors": [ + "Ryan Sandor Richards " + ], + "keywords": [ + "fastly", + "realtime", + "graph", + "chart", + "stats", + "visualization" + ], + "homepage": "https://fastly.github.io/epoch/", + "repository": { + "type": "git", + "url": "git://github.com/fastly/epoch.git" + }, + "dependencies": { + "d3": "^3.4.13" + } +} diff --git a/debian/missing-sources/epoch/composer.json b/debian/missing-sources/epoch/composer.json new file mode 100644 index 0000000..184efe0 --- /dev/null +++ b/debian/missing-sources/epoch/composer.json @@ -0,0 +1,22 @@ +{ + "name": "epochjs/epoch", + "description": "A general purpose, real-time visualization library.", + "keywords": [ + "epoch", + "d3", + "chart", + "graph", + "plot", + "real-time" + ], + "homepage": "https://github.com/epochjs/epoch", + "license": "MIT", + "authors": [ + { + "name": "Ryan Sandor Richards" + } + ], + "require": { + "mbostock/d3": "@stable" + } +} diff --git a/debian/missing-sources/epoch/gulpfile.js b/debian/missing-sources/epoch/gulpfile.js new file mode 100644 index 0000000..4f3b975 --- /dev/null +++ b/debian/missing-sources/epoch/gulpfile.js @@ -0,0 +1,108 @@ +'use strict';

+
+ +
+ + + + +
+

5. Single Series - Color Override

+

Change the bucket base color to orange and plot the Beta(2, 2) distribution.

+
+
+ + + + + + +
+

6. Multi Series - Normal + Beta

+

+ Plot the Beta(2,5) and Normal distributions as two layers in a single heatmap. Stream elements to the plot + by pressing the button. The normal distribution layer is in blue and the beta in green. +

+
+ +
+ + + +
+

1. Single Series

+

+ Correctly render a single series plot of y = cos(x) + 1 over the range [0, 2π]. +

+
+
+ + + + +
+

2. Single Series Single Transition

+

+ Correctly render a single series plot of y = sin(x) + 1. When the button is pressed push a new data point to the chart and correctly animate/render the transiton. +

+
+

+
+ + + + + +
+

3. Single Seires Stream

+

Correctly play / pause a single series stream of values from the plot y = cos(x) + 1.

+
+

+
+ + + + +
+

4. Multi Series

+

Correctly render a multi series plot of the following functions:

+
    +
  • y = log(x+1)
    • +
  • y = 2*log(x+1)
    • +
  • y = 3*log(x+1)
    • +
+
+
+ + + + + +
+

5. Multi Series Single Transition

+

+ Correctly render a multi series plot of the following functions: +

    +
  • y = x
    • +
  • y = x1.25
    • +
  • y = x1.5
    • +
+ and correctly render/animate the transiton after pressing the "Next" button. +

+
+

+ +

+
+ + + + +
+

6. Multi Seires Stream

+

+ Correctly play / pause a multi series stream of values over the following plots: +

    +
  • x
    • +
  • x * log(x)
    • +
  • x * log2(x)
    • +
+

+
+

+
+ + + + +
+

7. Color Override

+

The first layer should pink, the second green, and the third blue.

+
+
+ + + + + + +
+

8. Categorical Colors

+

Correctly render and switch between different categorical colors. Unlike with the basic charts this doesn't occur just by switching the class name on the containing element. The CSS query engine must be purge and the plot must be manually redrawn, like so:

+Epoch.QueryCSS.purge();
+chart.draw();
+
+

+ +
+ +

+ + + + +

+
+ + + + +
+

9. Show/Hide Layers

+
+

+ + + | + +

+
+ + + +
+

10. Fixed Range

+

+ Render a single series plot of y = cos(x). Instead of automatically setting the range to [-1, 1], the range is manually set to [-2, 5]. +

+
+
+ + + + +
+

11. Multi-axes

+

+ Render a plot that uses independent axes ranges for the left and + right sides. +

+
+
+ + + + +
+

12. Multi-axes with Labeled Ranges

+

+ Render a plot that uses independent axes ranges for the left and + right sides that are associated to labels in the chart data. +
