在图表内显示标签 - angular.js 和 chart.js

Question

我正在尝试显示图表的信息，而无需用户将鼠标悬停在图表的任何部分上。我正在使用 Chart.js 和 Angular.js

我的疑惑和这个question here!是一样的

html 代码：

<div class="wrapper-chart" >
        <canvas
            id="pie"
            class="chart chart-pie"
            chart-data="data"
            chart-labels="labels"
            chart-options="options"
            chart-colors="colors"
            legend = "true"
            chart-series="series">
    </canvas>
</div>

角度代码：

angular
    .module('myBeeApp.controllers')
    .controller('chartHome', chartHome);

chartHome.$inject = [
    '$scope'
];
function chartHome(
    $scope
){
        $scope.labels = ["Primavera", "Verão", "Outono", "Inverno"];
        $scope.data = [32, 53, 14, 79];
        $scope.options = {
            showToolTips: true,
            tooltipEvents: [],
            onAnimationComplete: function() {
                this.showTootip(this.datasets[0].bars,true);
            },
            title: {
                display: true,
                text: 'Quantidade por Estação',
                fontColor: '#ff8c1b',
                fontFamily: 'HelveticaNeue',
                fontSize: 26,
            },
            legend: {
                display: true
            },
            cutoutPercentage: 50,
        };
        $scope.colors = ["#FF7400", "#C85B00", "#FFB77B", "#E3831E"];
}

图表已正确生成，但尚未显示任何信息。

生成的图表（我的图表）：

我希望它是怎样的（带标签）：

我已经尝试过这段代码，但没有对我有用！

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

我也试过following these steps! 根本没用！（这就是为什么我认为这不是重复的问题）

版本：角度 - v1.6.6 ；角度图 - v1.1.1； chart.js - v2.7.1

感谢一切！

我关注了您提到的 Post。我更改了图表类型、标签、颜色和数据。它根据需要在图表中显示标签而无需悬停

angular.module('App', ["chart.js"]);


angular.module('App').controller('Controller', ['$scope', '$http', '$location', '$window',

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

    var diskDataJson = {
      "data": [32, 53, 14, 79],
      "labels": ["Primavera", "Verão", "Outono", "Inverno"],
      "colours": ["#FF7400", "#C85B00", "#FFB77B", "#E3831E"]
    };

    $scope.pieDiskData = diskDataJson;
  }
]);
