如何设置angularjs-chart的饼图样式,如下所示:
angularjs-chart上有一些示例,例如:
这个适合我的需要,我只需要改变颜色并使线条更细。就像上面那个。
我确实尝试过图表颜色和图表选项。第一个是根本不工作,我不知道如何使用选项。
这是代码:
控制器中的:
app.controller('DashboardController', function DashboardController ($scope) {
$scope.labels = ["Download Sales"];
$scope.data = [100];
});
在HTML中:
<canvas id="doughnut" class="chart chart-doughnut"
chart-data="data" chart-labels="labels">
</canvas>
答案 0 :(得分:2)
首先,您的 $scope.data
数组应为......
$scope.data = [
[100]
];
要设置/更改饼图/圆环图的颜色,请在中将 backgroundColor
属性设置为颜色值(s)的数组$scope.datasetOverride
强>
$scope.datasetOverride = [{
backgroundColor: ['#67d2c4']
}];
并且,为了使线更细,请将 cutoutPercentage
属性设置为 $scope.options
(瘦度) >
$scope.options = {
cutoutPercentage: 80
}
另外,请务必在HTML标记中添加 chart-dataset-override
指令。
::工作示例::
var app = angular.module('app', ['chart.js']);
app.controller("DashboardController", function($scope) {
$scope.labels = ["Download Sales"];
$scope.data = [
[100]
];
$scope.options = {
cutoutPercentage: 80 //set as you wish
}
$scope.datasetOverride = [{
backgroundColor: ['#67d2c4']
}];
});
