Template for shared modules in angular2
npm install shared-test1> Angular2 charting components based on Highcharts. Live Demo




npm install angular2-highcharts --save
`
The full installation process depends on environment you are using to run your angular2 app. Here are some examples:
- angular2-webpack-starter (Webpack)
- angular/quickstart (SystemJS)
Usage

#### Setup App Module
`TypeScript
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { ChartModule } from 'angular2-highcharts';
import { App } from './App';@NgModule({
imports: [BrowserModule, ChartModule],
declarations: [App],
bootstrap: [App]
})
export class AppModule {}
`#### Create First Chart Component
Main charts functionality provided by the
chart component and its options property.`TypeScript
import { Component } from '@angular/core';@Component({
selector: 'simple-chart-example',
template:
})
export class App {
constructor() {
this.options = {
title : { text : 'simple chart' },
series: [{
data: [29.9, 71.5, 106.4, 129.2],
}]
};
}
options: Object;
}

Highcharts itself provides bunch of events, and you still can use them with angular2-higcharts via the options property of the chart component. But it is not an angular2 way to handle events like this. So that angular2-higcharts provides EventEmitter 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 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);
}
`
Live Demo
#### 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 API`HTML
{{serieName}} is hovered
`
`TypeScript
onSeriesMouseOver (e) {
this.serieName = e.context.name;
}
`
Live Demo
#### Point Events Similary you can use the
point to access to options.plotOptions.series.point.events API.
`HTML
{{point}} is selected
`
Live Demo
#### Axis Events Similary you can use the
xAxis or yAxes to access to options.xAxis.events or options.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;
}

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;
}
}

The Highchart modules are not really ES6 compatiable so access to highcharts native API depends on environment configuration

The type property allows you to specify chart type. Possible values are:
* Chart (Default value)
* StockChart
* Map (To use this type you need to load the 'highcharts/modules/map' module additionally. Live Demo)`TypeScript
@Component({
selector: 'stock-chart-example',
directives: [CHART_DIRECTIVES],
template:
})
export class StockChartExample {
constructor(jsonp : Jsonp) {
jsonp.request('https://www.highcharts.com/samples/data/jsonp.php?filename=aapl-c.json&callback=JSONP_CALLBACK').subscribe(res => {
this.options = {
title : { text : 'AAPL Stock Price' },
series : [{
name : 'AAPL',
data : res.json(),
tooltip: {
valueDecimals: 2
}
}]
};
});
}
options: Object;
}

##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 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 for dynamic manipulations with chart and angular-highcharts` provides you access to the original chart object.
