angularjs - 如何在 Angular 图表js中的每个条上设置单色

这是我的html代码：

<canvas id="bar" class="chart chart-bar"
            chart-data="expenseData" chart-labels="labels" chart-series="series" chart-options="chartOptions" colours= "colours">

    </canvas>

这是js代码：

var setGraphDate = function () {
        var xData = [];
        var yData = [];
        $scope.Data.ExpenseRecords.forEach(function (g) {
            yData.push(g.PercentOfCompletion);
            xData.push(g.TspShortName);
        });
        $scope.colours = "rgba(224, 108, 112, 1)";
        $scope.labels = xData;
        $scope.expenseData = yData;
        $scope.series = ['Expense Graph'];
        $scope.chartOptions = {

            legend: {
                display: false
            },

            },
            title: {
                display: true,
                text: 'TSP Burn Rate'
            },

            // Option to show VALUES on chart
            events: false,
            tooltips: {
                enabled: false
            },
            hover: {
                animationDuration: 0
            }
    };

angularjs - 如何在 Angular 图表js中的每个条上设置单色-LMLPHP

每个条的颜色是不同的，并且在每次重新加载时也会改变。

我只希望所有条形都是蓝色。

最佳答案

用

chart-dataset-override="colors"

演示

angular.module("app", ["chart.js"]).controller("DoughnutCtrl", function ($scope) {
  $scope.results = {'1': 0, '2': 0, '3': 0, '4': 0, '5': 0, '6': 0, '7': 0, '8': 0, '9': 0, '10': 0};
  $scope.labels = ['1', '2', '3', '4', '5', '6', '7', '8', '9', '10'];

  $scope.data = [
    [1, 3, 5, 8, 9, 10, 11, 12, 33, 5]
  ];
  $scope.colors = [{
    fillColor: 'rgba(59, 89, 152,0.2)',
    strokeColor: 'rgba(59, 89, 152,1)',
    pointColor: 'rgba(59, 89, 152,1)',
    pointStrokeColor: '#fff',
    pointHighlightFill: '#fff',
    pointHighlightStroke: 'rgba(59, 89, 152,0.8)'
  }];
});
