Beautiful, reactive, responsive charts for Angular.JS using [Chart.js](http://www.chartjs.org/).
Have a look at the [demo site](http://jtblin.github.io/angular-chart.js/) to see examples with detailed markup,
script and options.
# Installation
This is the `1.x` branch which requires Chart.js 2.x version. Following semantic versioning,
there are numerous **breaking changes** since 0.x, notably:
* all options now need to use the `chart-` prefix
* `chart-colours` is now `chart-colors` and `chart-get-colour` is now `chart-get-color`
* chart types are in `camelCase` e.g. `line` and `polarArea`
* legend is now a Chart.js option so the `chart-legend` attribute has been removed
* events emitted on creation and update are now prefixed with `chart-` e.g. `chart-create`
* `$scope.$apply` is not called anymore on mouse hover functions calls
* obviously all Chart.js breaking changes as well in how options are set, etc.
* disabling the `responsive` option doesn't work via global `Chart.defaults.global.responsive` anymore,
but must be set via standard options e.g. `ChartJsProvider.setOptions({ responsive: false });`
* factory now returns a module name instead of a module instance
### npm
npm install --save angular-chart.js
### cdn
//cdn.jsdelivr.net/angular.chartjs/latest/angular-chart.min.js
### bower
bower install --save angular-chart.js
### manually
or copy the files from `dist/`.
Then add the sources to your code (adjust paths as needed) after
adding the dependencies for Angular and Chart.js first:
```html
...

```
# Utilisation
There are 8 types of charts so 8 directives: `chart-line`, `chart-bar`, `chart-horizontal-bar`, `chart-radar`,
`chart-pie`, `chart-polar-area`, `chart-doughnut`, `chart-bubble`.
Here are the options for all directives:
- `chart-data`: series data
- `chart-labels`: x axis labels (line, bar, horizontal bar, radar, bubble) or series labels (pie, doughnut, polar area)
- `chart-options`: chart options (as from [Chart.js documentation](http://www.chartjs.org/docs/))
- `chart-series`: (default: `[]`): series labels (line, bar, radar)
- `chart-colors`: data colors (will use default colors if not specified)
- `chart-get-color`: function that returns a color in case there are not enough (will use random colors if not specified)
- `chart-click`: onclick event handler
- `chart-hover`: onmousemove event handler
- `chart-dataset-override`: override individual datasets to allow per dataset configuration e.g. y-axis, mixed type chart
There is another directive `chart-base` that takes an extra attribute `chart-type` to define the type
dynamically.
You can create mixed type chart using the `chart-dataset-override`, see
[bar-line example](http://jtblin.github.io/angular-chart.js/examples/dataset-override.html).
See also [stacked bar example](http://jtblin.github.io/angular-chart.js/examples/stacked-bars.html).
# Example
## Markup
```html
```
## Javascript
```javascript
angular.module("app", ["chart.js"])
// Optional configuration
.config(['ChartJsProvider', function (ChartJsProvider) {
// Configure all charts
ChartJsProvider.setOptions({
chartColors: ['#FF5252', '#FF8A80'],
responsive: false
});
// Configure all line charts
ChartJsProvider.setOptions('line', {
showLines: false
});
}])
.controller("LineCtrl", ['$scope', '$timeout', function ($scope, $timeout) {
$scope.labels = ["January", "February", "March", "April", "May", "June", "July"];
$scope.series = ['Series A', 'Series B'];
$scope.data = [
[65, 59, 80, 81, 56, 55, 40],
[28, 48, 40, 19, 86, 27, 90]
];
$scope.onClick = function (points, evt) {
console.log(points, evt);
};
// Simulate async data update
$timeout(function () {
$scope.data = [
[28, 48, 40, 19, 86, 27, 90],
[65, 59, 80, 81, 56, 55, 40]
];
}, 3000);
}]);
```
## AMD RequireJS
See [a simple AMD example](examples/amd.js)
## CommonJS e.g. webpack
Module should work with CommonJS out of the box e.g. [browserify](http://browserify.org/) or
[webpack](http://webpack.github.io/), see a [webpack example](examples/webpack.commonjs.js).
# Reactive
angular-chart.js watch updates on data, series, labels, colors and options and will update, or destroy and recreate,
the chart on changes.
# Events
angular-chart.js listens to the following events on the `scope` and acts accordingly:
* `$destroy`: call `.destroy()` on the chart
* `$resize`: call `.resize()` on the chart
angular-chart.js emits the following events on the `scope` and pass the chart as argument:
* `chart-create`: when chart is created
* `chart-update`: when chart is updated
* `chart-destroy`: when chart is destroyed
```
$scope.$on('chart-create', function (evt, chart) {
console.log(chart);
});
```
**Note**: the event can be emitted multiple times for each chart as the chart can be destroyed and
created multiple times during angular `watch` lifecycle.
angular-chart.js listens to the scope `$destroy` event and destroys the chart when it happens.
# Colors
There are a set of 7 default colors. Colors can be replaced using the `colors` attribute.
If there is more data than colors, colors are generated randomly or can be provided
via a function through the `getColor` attribute.
Hex colors are converted to Chart.js colors automatically,
including different shades for highlight, fill, stroke, etc.
## Browser compatibility
For IE8 and older browsers, you will need
to include [excanvas](https://code.google.com/p/explorercanvas/wiki/Instructions).
You will also need a [shim](https://github.com/es-shims/es5-shim) for ES5 functions.
You also need to have ```height``` and ```width``` attributes for the ```
