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

Install the library with `npm install cfpb-chart-builder` and then:

```js

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',

});

```

## API

### `createChart( options )`

Create a CFPB chart.

Config options can be passed as an argument to `createChart` or as a data attribute on

an element with a class of `cfpb-chart` (see above).

**options.el**: `Element`

Required. Reference to the DOM element in which to render the chart.

**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`.

**options.title**: `String`

Optional. Title of the chart.

**options.color**: `String`

Optional. Chart's color scheme.

Options: `blue`, `green`, `teal`, `navy`, `purple`, `neutral`, `gold`.

If omitted, the chart color will be black.

**options.metadata**: `String|Object`

Optional. Arbitrary metadata for your chart.

For example, `bar` charts currently require a group key (e.g. `Number of Loans`) to filter data.

**options.yAxisLabel**: `String`

Optional. Hardcoded y-axis label for the chart.

**options.tooltipFormatter**: `Function`

Optional. Function that returns HTML to format the chart's tooltip.

See Highcharts' [tooltip.formatter](http://api.highcharts.com/highmaps/tooltip.formatter).

**options.pointDescriptionFormatter**: `Function`

Optional. Formatter function to use instead of the default for point descriptions.

See Highcharts' [accessibility.pointDescriptionFormatter](http://api.highcharts.com/highmaps/accessibility.pointDescriptionFormatter).

**options.seriesDescriptionFormatter**: `Function`

Optional. Formatter function to use instead of the default for series descriptions.

See Highcharts' [accessibility.seriesDescriptionFormatter](http://api.highcharts.com/highmaps/accessibility.seriesDescriptionFormatter).

**options.screenReaderSectionFormatter**: `Function`

Optional. A formatter function to create the HTML contents of the hidden screen

reader information region. See Highcharts' [accessibility.screenReaderSectionFormatter](http://api.highcharts.com/highmaps/accessibility.screenReaderSectionFormatter).

### `chart.update( options )`

Update a CFPB chart.

Provide any of the above options and the chart will be redrawn with those new settings.

## Contributing

We welcome your feedback and contributions. See the

[contribution guidelines](https://github.com/cfpb/open-source-project-template/blob/main/CONTRIBUTING.md)

for more details.

### Install locally

1. Install [Node.js 8](http://nodejs.org) however you'd like.

2. Install [Gulp](http://gulpjs.com): `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](#development-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 run the site on a local server,

run `gulp watch` from the project root.

Running in this manner will also watch for changes in the source code

and automatically update the running site.

#### Development with cfgov-refresh

When running the site locally, you can temporarily link changes you are making to the code with the [cfgov-refresh](https://github.com/cfpb/cfgov-refresh/) project.

1. In the cfpb-chart-builder directory, run:

   ```

   npm link

   ```

1. In the cfgov-refresh directory:

   ```

   ./setup.sh

   npm link cfpb-chart-builder

   gulp build

   ./runserver.sh

   ```

1. When you're done and want to bring back the published package:

   ```

   npm unlink cfpb-chart-builder

   yarn add cfpb-chart-builder

   gulp build

   ```

### Publish a release

1. After merging all PRs needed for release, update the version in `package.json` using [semantic versioning](https://semver.org). This command will also tag and commit the updated version:

   ```

   # change patch to minor or major as needed

   npm version patch

   ```

1. Push the new version and tag to Github:

   ```

   git push upstream main --tags

   ```

1. Create a new release description on Github at https://github.com/cfpb/cfpb-chart-builder/releases/new using your new tag.

1. Publish to npm:

   ```

   npm publish

   ```

## Testing

`npm test` will run unit and browser tests.

Sauce Labs is used to test the charts in IE 10.

_(Note: This is not working correctly as of 1/24/19.)_

An [Open Sauce](https://saucelabs.com/open-source) 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`

1. 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/` in IE VMs and reports any `window` errors.
