我看过如何更改Angular-Chart.js的颜色,但它与整个(数据集)的颜色有关,而不是特定的栏.

我正在寻找的是一种在条形图中为每个条形应用不同颜色的方法; ChartJS到Angular.

所以,我有一个条形图:

<canvas id="locationBar" class="chart chart-bar" data="chartParams.votes" labels="chartParams.listOfLocations" series="chartParams.series" colours="chartParams.colours" options="chartParams.options"></canvas> 

使用以下角度代码(当然在控制器中)

$scope.chartParams = {
    listOfLocations: ['Trenzalore','Earth','Caprica','Sol','Tau Ceti'],
    votes: [[5,10,6,7,2]],
    series: ["Nice Places"],
    colours: [{fillColor:getRandomColour()}],
    options: {barShowStroke : false}
};

哪里getRandomColour()会返回一个随机颜色.

现在,该colours字段将此颜色应用于所有条形:

当我真的想要每个酒吧有不同的颜色时:

Plunker

我正在我正在进行的项目中使用angular-chartJS,并且我需要为条形图中的每个条形图使用不同的颜色.

帆布:

<canvas id="bar" class="chart chart-bar" data="medal_data" labels="medal_ticks"></canvas>

控制器:

$scope.medal_ticks = ['Gold', 'Silver', 'Bronze', 'Not passed'];
$scope.series = ['Medaljer'];
$scope.medals_colours= ['#087D76', '#B3BC3A', '#38B665', '#8B4A9D'];

$scope.medal_data = ['1', '5', '2', '0'];

我试图将属性添加colours="medals_colours"到我的画布,唯一的问题是它只使用数组中的第一种颜色,我想要的是每种颜色代表每一列.所以,#087D76用于表示Gold,#B3BC3A对Silver等

我的Html:

<div class="graph-display" ng-controller="jsonServerBox">
    <div class="bar-chart-box" ng-repeat="module in ocw.modules"> 
        <canvas class="chart chart-bar" data="{{module.data}}" labels="{{module.labels}}" series="{{module.series}}"></canvas>
    </div>
</div>

我的JS:

app.controller('jsonServerBox', function($scope, $http) {
  var json = $http.get('serverbox.json').then(function(res){
          return res.data;
        });
  $scope.ocw = json;    
    });

图表没有显示,不知道为什么？我也没有在控制台中出现任何错误.

更新:我的JSON文件内容

[{"modules":[
            {
               "series":"SeriesA",
               "data":["90", "99", "80", "91", "76", "75", "60", "67", "59", "55"],
               "labels":["01", "02", "03", "04", "05", "06", "07","08","09","10"]
            },

            {
               "series":"SeriesB",
               "data":["90", "99", "80", "91", "76", "75", "60", "67", "59", "55"],
               "labels":["01", "02", "03", "04", "05", "06", "07","08","09","10"]
