` wrappers for highcharts events. `ChartEvent` is an angular2-higcharts class which simply wraps original Highcharts events (`chartEvent.originalEvent`) and adds event handler context (`chartEvent.context`) since it differs depending on events.
#### Chart Events
All the events from the [options.chart.events](http://api.highcharts.com/highcharts#chart.events) are available as output properties of the `chart` component.
```HTML
```
```TypeScript
onChartSelection (e) {
this.from = e.originalEvent.xAxis[0].min.toFixed(2);
this.to = e.originalEvent.xAxis[0].max.toFixed(2);
}
```

#### Series Events
To use series events the same way you need to add the `series` component as a child of your chart. The only purpose of this auxiliary component is to provide access to [options.plotOptions.series.events](http://api.highcharts.com/highcharts#plotOptions.series.events) API
```HTML
{{serieName}} is hovered
```
```TypeScript
onSeriesMouseOver (e) {
this.serieName = e.context.name;
}
```

#### Point Events
Similary you can use the `point` to access to [options.plotOptions.series.point.events](http://api.highcharts.com/highcharts#plotOptions.series.point.events) API.
```HTML
{{point}} is selected
```

#### Axis Events
Similary you can use the `xAxis` or `yAxes` to access to [options.xAxis.events](http://api.highcharts.com/highcharts#xAxis.events) or [options.yAxis.events](http://api.highcharts.com/highcharts#yAxis.events) API.
```HTML
{{minX}} - {{maxX}}
{{minY}} - {{maxY}}
```
```TypeScript
onAfterSetExtremesX (e) {
this.minX = e.context.min;
this.maxX = e.context.max;
}
onAfterSetExtremesY (e) {
this.minY = e.context.min;
this.maxY = e.context.max;
}
```

### Dynamic Interaction with Chart Object
angular2-higcharts provides possibility to interact with native `HighchartsChartObject` chart object.
```TypeScript
@Component({
selector: 'my-app',
directives: [CHART_DIRECTIVES],
template: `
`
})
class AppComponent {
constructor() {
this.options = {
chart: { type: 'spline' },
title: { text : 'dynamic data example'}
series: [{ data: [2,3,5,8,13] }]
};
setInterval(() => this.chart.series[0].addPoint(Math.random() * 10), 1000);
}
chart : Object;
options: Object;
saveInstance(chartInstance) {
this.chart = chartInstance;
}
}
```

### Highstock
```
```
Also you need to change your `@NgModule` setup.
```diff
...
@NgModule({
...
imports: [
BrowserModule,
ChartModule.forRoot(
- require('highcharts'),
+ require('highcharts/highstock')
)
]
})
```
👉 [Live Demo](http://plnkr.co/edit/2xSewTZ9b213vA0ALmFq?p=preview)
### Highmaps
```
```
Also you need to change your `@NgModule` setup.
```diff
...
@NgModule({
...
imports: [
BrowserModule,
ChartModule.forRoot(
- require('highcharts'),
+ require('highcharts/highmaps')
)
],
})
```
👉 [Live Demo](http://plnkr.co/edit/AmDfKwhRhshFn3CPprkk?p=preview)
### Add Highcharts Modules
Any other modules like highcharts-3d, highcharts-exporintg and etc. can be also added in `@NgModule` after main chart module
```diff
...
@NgModule({
...
imports: [
BrowserModule,
ChartModule.forRoot(
require('highcharts'),
+ require('highcharts/highchart-3d'),
+ require('highcharts/modules/exporting')
)
],
})
```
Check out structure of the `node-modules/highcharts` folder to find necessary module.

### Access to the Highcharts Static API
```diff
...
const Highcharts = require('highcharts');
Highcharts.setOptions({
colors: ['#50B432']
});
@NgModule({
...
imports: [
BrowserModule,
ChartModule.forRoot(
- require('highcharts'),
+ Highcharts
)
],
})
```

##FAQ
#### Why don't my series, title, axes and etc redraw after I update initial options ?
Because `angular-highcharts` is just a thin wrapper of the [Highcharts](http:/ /www.highcharts.com/) library and doesn't bind to initial options. I understand that you expect more angular-way behaviour like data binding with appropriate redrawing. But it is barely possible to implement it without redundant complications and performance decrease because almost all options can be dynamic. So my idea was to avoid any additional logic more than just a sugar (like events for series and options). In the other hand Highcharts has great [API](http://api.highcharts.com/highcharts#Chart) for dynamic manipulations with chart and `angular-highcharts` [provides you access](#dynamic-interaction-with-chart-object) to the original chart object.
