Question

我正在Ionic 3做一个项目，需要在其中使用一个仪表。

这些例子是离子2，很难理解和整合它。任何人都可以解释如何解决这个问题？如果有人有工作指标，请分享代码。这对每个人都有帮助。

Answer 1

我有一个非常复杂的。它既有量又有馅饼。换句话说，自定义组件。但是你可以轻松地使用那个小提琴手来理解这个想法。

注意： 我已将我的工作代码放在此处。请根据需要进行调整。

由于您使用Ionic3/ Angular，因此您可以使用这些npm packages：

npm i highcharts - -save

npm i highcharts-more - -save

npm i highcharts-solid-gauge  - - save

HTML 的

 <div [id]="data?.chartId" class="my-chart"></div>

TS

import * as HighCharts from 'highcharts';
import HighchartsMore from 'highcharts-more';
HighchartsMore(HighCharts);

constructor(){}

showChart(totalOfBudgetAndContingency: number, paidPercentage: number, remainingPercentageExcludingPaid: number, contingencyPercentage: number,
    spent: number, spentOnChart: number, remainingAmount: number, daysToGo: number, spentOverColor: string, chartId: string) {
    let chart = HighCharts.chart(chartId, {

这是有效的Fiddler

使用离子3中的量规
