如何在角图表条形图中使用纯色条 [英] How to have solid colored bars in angular-chart bar chart
问题描述
我正在使用角度图表（基于chart.js）创建一些条形图，但我无法获得我想要的条形图。我希望这些条形是这样的纯色：
I'm using angular-chart (based on chart.js) to create some bar charts and am having trouble getting the bar styling I want. I want the bars to be solid colors like this:
但我无法弄清楚如何摆脱chart.js默认添加的alpha：
But I can't figure out how to get rid of the alpha that chart.js adds by default:
我的html如下所示：
My html looks like this:
<body ng-app="myApp" ng-controller="myController as ctrl">
<canvas id="outreach" class="chart chart-bar"
chart-labels="ctrl.socialChart.labels"
chart-data="ctrl.socialChart.data"
chart-series="ctrl.socialChart.series"
chart-colors="ctrl.socialChart.colors"
chart-options="ctrl.socialChart.options"></canvas>
</body>
javascript：
And the javascript:
angular.module('myApp', ['chart.js'])
.controller('myController', [function() {
var ctrl = this;
ctrl.socialChart = {
options: {
legend: {
display: true
}
},
labels: ['2012'],
series: ['FACEBOOK', 'GOOGLE', 'TWITTER', 'INSTAGRAM'],
// colors: ['rgba(237, 64, 42, 1)', 'rgba(240, 171, 5, 1)', 'rgba(160, 180, 33, 1)', 'rgba(0, 163, 159, 1)'],
colors: ['#ED402A', '#F0AB05', '#A0B421', '#00A39F'],
data: [[1178], [652], [1004], [838]]
}
}]);
这是一个Plunker演示它： Plunker

我发现了很多关于使用rgba表示法的信息（出于某种原因给出了我完全错了颜色和fillColor（我根本无法工作）。很难说出chart.js版本1或2的信息是什么。
I've found lots of information about using rgba notation (which for some reason gives me the wrong colors altogether) and fillColor (which I can't get working at all). It's hard to tell what info is for version 1 or 2 of chart.js.
任何帮助都将不胜感激。
Any help would be appreciated.
推荐答案
您可以使用 chart-dataset-override =datasetOverride
HTML
<div ng-controller="BarCtrl">
<canvas id="bar" class="chart chart-bar"
chart-data="data"
chart-labels="labels"
chart-series="series"
chart-dataset-override="datasetOverride"></canvas>
</div>
控制器
ctrl.datasetOverride = [{
fill: true,
backgroundColor: [
"#ED402A",
"#36A2EB",
"#FFCE56"
]
}, {
fill: true,
backgroundColor: [
"#F0AB05",
"#36A2EB",
"#FFCE56"
]
}, {
fill: true,
backgroundColor: [
"#A0B421",
"#36A2EB",
"#FFCE56"
]
}, {
fill: true,
backgroundColor: [
"#00A39F",
"#36A2EB",
"#FFCE56"
]
},
];
