这里是在ionic2下使用highchairs和chart.js的简单示例
chartjs部分参考http://www.jianshu.com/p/bc18132da812
1.安装hightcharts
npm install highcharts --save
typings install dt~highcharts --global --save
2.编辑
html文件
在html中添加一个div来显示图表
ts文件
import {Component,ElementRef,AfterViewInit,OnDestroy,ViewChild} from '@angular/core';
import {NavController} from 'ionic-angular';
import * as CHartJs from 'chart.js'; //charts图表
import * as Highcharts from 'highcharts' //highcharts图表
@Component({
templateUrl: 'build/pages/plus/plus.html',
})
export class PlusPage implements AfterViewInit, OnDestroy{
constructor(private navCtrl:NavController){}
@ViewChild('chart') public chartEl: ElementRef; //highcharts
private _chart: any; //highcharts
//highcharts
public ngAfterViewInit() {
let opts: any = {
title: {
text: 'Monthly Average Temperature',
x: -20
},
xAxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
},
series: [{

data: [
7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2,
26.5, 23.3, 18.3, 13.9, 9.6
]
},

5.0, 6.9, 1.5, 14.5, 18.2, 21.5, 25.2,
26.5, 11.3, 25.3, 127.9, 10.6
]
}
]
};
if (this.chartEl && this.chartEl.nativeElement) {
opts.chart = {
type: 'line',
renderTo: this.chartEl.nativeElement
};
this._chart = new Highcharts.Chart(opts);
}
}
public ngOnDestroy() {
this._chart.destroy();
}
//chart.js
ionViewDidEnter(){
var canvas = document.getElementById("myChart");
var ctx = canvas.getContext('2d');
CHartJs.Line(ctx,{
