Angular Highcharts:百分比面积图(Percentage Area Chart)
现在,让我们看一个百分比面积图的例子。
plotOptions
plotOptions是每个系列类型的配置对象的包装对象。如系列数组中给出的,可以为每个系列项覆盖配置对象。这是将每个系列的值叠加在一起。
使用plotOptions.area.stacking配置图表堆叠为“normal”。允许的值:null将禁用堆叠,"normal"按值堆叠,"percent"按百分比堆叠图表。
var plotOptions = {
area: {
stacking: 'percent',
lineColor: '#666666',
lineWidth: 1,
marker: {
lineWidth: 1,
lineColor: '#666666'
}
}
};例子
app.component.ts
import { Component } from '@angular/core';
import * as Highcharts from 'highcharts';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
highcharts = Highcharts;
chartOptions = {
