Installation

Add a div with a class of cfpb-chart and the following data attributes to your page:

<div class="cfpb-chart"
     data-chart-type="line"
     data-chart-title="Number of Originations (in millions)"
     data-chart-description="Auto loan originations decreased in 2016."
     data-chart-color="green"
     data-chart-metadata="Number of Loans"
     data-chart-source="consumer-credit-trends/auto-loans.csv">
     Auto loan originations decreased in 2016.
</div>

Add the library to your page:

<script type="text/javascript" src="dist/cfpb-chart-builder.min.js"></script>

It'll generate a chart for you:

You can also manually initialize a chart by providing a target element:

const ccb = require( 'cfpb-chart-builder' );

const chart = ccb.createChart({
  el: document.getElementById('my-chart-div'),
  source: 'http://mywebsite.com/api/data.json',
  type: 'line',
  color: 'green'
});

// Charts can be updated and redrawn
chart.update({
  source: 'http://mywebsite.com/api/some-other-data.json',
});

options.type: String

Required. Type of chart to render. Options: line, line-comparison, bar or tile_map.

options.source: String

Required. Location of data (JSON) to download and add to chart series. Can be relative or absolute URL. If relative, the value of window.CFPB_CHART_DATA_SOURCE_BASE will be prepended to it.

Multiple data sources can be provided by separating them with semicolons. E.g. mortgage/national.json;mortgage/nyc.json.

Optional. Title of the chart.

options.color: String

Optional. Chart's color scheme. Options: blue, green, teal, navy.

options.metadata: String|Object

Install locally

1. Install Node.js 8 however you'd like.
2. Install Gulp: npm install -g gulp
3. Install the dependencies and compile the project with: ./setup.sh

NOTE: To re-install and rebuild all the site’s assets run ./setup.sh again. See the usage section on updating all the project dependencies.

Development usage

Each time you fetch from the upstream repository (this repo), run ./setup.sh. This setup script will remove and re-install the project dependencies and rebuild the site's JavaScript and CSS assets.

To watch for changes in the source code and automatically update the running site, open a terminal and run:

gulp watch

Testing

npm test will run unit and browser tests.

Sauce Labs is used to test the charts in IE 8 through 10. An Open Sauce account has been created for this repo. Its credentials can be found at https://GHE/gist/contolini/504ea71f6a19c74090c7a150aff60421. Add the credentials locally by doing:

1. cp test/config.json.example test/config.json
2. Add valid Sauce Labs credentials to test/config.json (see above gist).

The browser tests will take several minutes to run. The test script simply loads http://localhost:8089/test in IE VMs and reports any window errors.
