如何在角度图表条形图中有纯色条中有、纯色、图表、角度
我正在使用 angular-chart(基于 chart.js)创建一些条形图，但无法获得我想要的条形样式.我希望条形图是这样的纯色:
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:
但我不知道如何摆脱 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 看起来像这样:
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>
还有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]]
}
}]);

我发现了很多关于使用 rgba 表示法(由于某种原因，它给了我完全错误的颜色)和 fillColor(我根本无法使用)的信息.很难判断 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.
任何帮助将不胜感激.
推荐答案
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"
]
},
];
