Angular-Charts - 饼图，在每个数据片段内显示标签 [英] Angular-Charts - Pie Chart,show labels inside each slice of data

问题描述

我正在学习角度图表-js的阶段。我试图使用angular-chart.js绘制饼图。但是我无法找到在饼图上显示标签（不是工具提示）的方法，它描述了每个数据片段。

以下是我的方法：

  angular.module（'App'）。controller（'Controller'，['$ scope'，'$ http'，'$ location'，'$ window'，'$ routeParams'，函数（$ scope，$ http，$ location，$ window）{var diskDataJson = {data：[80,12]，labels：[已用空间，可用空间]，颜色：['＃9AB6F0' ，'＃C2D3F6']}; $ scope.pieDiskData = json;}]）;  

 < script src =https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js>< / script>< table border =0width =100％> < TR> < td style =border-left：1px solid＃0099CCwidth =25％> < center>< span>< label ng-bind-html ='load.static.dashboard.system.DUSAGE'| translate/>< / span> < /中心]，[ < canvas id =pie33class =chart chart-pie chart-xs ng-isolate-scopeheight =120width =240data =pieDiskData.datalabels =pieDiskData.labelscolors = pieDiskData.colourslegend =true>< / canvas> < / TD> < / tr>< / table>

I am learning stage of angular-chart-js. I am trying to use angular-chart.js to plot a pie chart. But I am unable to find a way for showing labels (not tooltips) on the pie chart, which describe each slice of data.

Here is how I did it:

angular.module('App').controller('Controller', ['$scope', '$http', '$location', '$window', '$routeParams',
    function($scope, $http, $location, $window) {
        var diskDataJson = {
            "data": [80, 12],
            "labels": [Used space, Free Space],
            "colours": ['#9AB6F0', '#C2D3F6']
        };
    
        $scope.pieDiskData = json;
    }
]);

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<table border="0" width="100%">
  <tr>
    <td style="border-left: 1px solid #0099CC" width="25%">
      <center><span><label ng-bind-html="'load.static.dashboard.system.DUSAGE' | translate"/></span>
      </center>
      <canvas id="pie33" class="chart chart-pie chart-xs ng-isolate-scope" height="120" width="240" data="pieDiskData.data" labels="pieDiskData.labels" colours="pieDiskData.colours" legend="true"></canvas>
    </td>
  </tr>
</table>

Adapted from https://stackoverflow.com/a/25913101/360067 for angular-chart

Add the following options to your scope

$scope.options = {
    tooltipEvents: [],
    showTooltips: true,
    tooltipCaretSize: 0,
    onAnimationComplete: function () {
        this.showTooltip(this.segments, true);
    },
};

And use that in your directive

<canvas id="pie33" options="options"...
