import {NavController, NavParams} from 'ionic-angular';
import ECharts from 'echarts';
@Component({

})
export class EchartsDemoPage {
@ViewChild('chart') chart: ElementRef;
constructor(public navCtrl: NavController, public navParams: NavParams) {
}
ionViewDidEnter() {
this.initChart();
}
initChart() {
let element = this.chart.nativeElement;
element.style.width = (document.body.clientWidth - 16) + 'px';//设置容器宽度
let myChart = ECharts.init(element);
myChart.setOption({
tooltip: {
trigger: 'item',
formatter: "{a} <br/>{b}: {c} ({d}%)"
},
legend: {
