D3 Financial Components (D3FC)

A collection of components that make it easy to build interactive financial charts with D3.

Installation

D3FC and its dependencies (D3, css-layout) are available via npm. Simply install as follows:

npm install d3-financial-components

Once installed, you can reference the D3FC JavaScript, CSS and dependencies within an HTML page as follows:

<script src="node_modules/d3-financial-components/node_modules/d3/d3.js"></script>
<script src="node_modules/d3-financial-components/node_modules/css-layout/src/Layout.js"></script>
<script src="node_modules/d3-financial-components/dist/d3-financial-components.js"></script>

<link href="node_modules/d3-financial-components/dist/d3-financial-components.css" rel="stylesheet"/>

If you want a quick verification that everything has installed correctly, the following code will render a simple time series chart:

<div id="chart"></div>
<script type="text/javascript">
var data = fc.dataGenerator()(50);

var chart = fc.charts.linearTimeSeries()
    .xDomain(fc.utilities.extent(data, 'date'))
    .xTicks(5)
    .yDomain(fc.utilities.extent(data, ['high', 'low']))
    .yNice()
    .yTicks(5);

var gridlines = fc.scale.gridlines();
var candlestick = fc.series.candlestick();
var movingAverage = fc.indicators.movingAverage();

var multi = fc.series.multi()
    .series([gridlines, candlestick, movingAverage]);
chart.plotArea(multi);

d3.select("#chart")
    .append('svg')
    .style({
        height: '250px',
        width: '600px'
    })
    .datum(data)
    .call(chart);

</script>

Developing

npm, the package manager for Node.js, is used to manage the project's dependencies. Grunt, a JavaScript task runner, is used to test and build the project.

Initial Setup

• Download or clone this repository locally
• Ensure Node.js, which includes npm, is installed
• Ensure Grunt is installed:

npm install -g grunt-cli

• Navigate to the root of your local copy of this project and install the dependencies:

npm install

• Perform an initial build:

grunt

Grunt Tasks

The following Grunt tasks, found in Gruntfile.js, can be run from the command line. The most commonly used tasks to build and develop the project are:

• grunt build - generate the project's JavaScript and CSS files in the dist directory (at the root of the project); build the visual tests
• grunt dev - run grunt build, then grunt watch
• grunt dev:serve - same as grunt dev but also starts a web server for viewing the visual tests

Other tasks include:

• grunt check - run JSHint and JSCS checks
• grunt test - run unit tests and build the visual tests
• grunt watch - watch the source files and rebuild when a change is saved
• grunt serve - start a web server for viewing the visual tests
• grunt - check, test and build the project

Visual Tests

The project includes a number of unit tests, however, because these components are visual in nature, unit testing is not enough. This project contains a number of ad-hoc visual tests that are found within the visual-tests folder. The visual tests are compiled, via assemble, to create a simple website. To view this site, run grunt serve or a static server from the visual-tests\dist folder.
