Ima*_*lea 8 javascript canvas angularjs chart.js
我正在尝试使用angular-chartjs库但遇到了一些问题.页面上没有错误.但画布是空的.
有人有想法吗？我尝试过几次重新排序脚本.我只是想不出来.:(
这是html.
<html ng-app="profitly">
<head>
<script src="js/lib/jquery.min.js"></script>
<script src="js/lib/Chart.js"></script>
<script src="js/lib/angular.min.js"></script>
<script src="js/lib/angular-route.min.js"></script>
<script src="js/lib/angular-chartjs.min.js"></script>
<script src="js/controller.js"></script>
</head>
<body ng-controller="MainController" class="container-fluid">
<div class="wrapper" ng-view>
<article ng-controller="graph">
<cjs-doughnut dataset="someData" options="someOptions" segment-stroke-width="5"></cjs-doughnut>
</article>
</div>
</body>
<html>
这是应用程序初始化:
var app = angular.module('profitly', ['ngRoute', 'chartjs']);
以下是此部分的控制器:
app.controller('graph', function($scope) {
$scope.someData = {
labels: [
'Supply',
'May',
'Jun'
],
datasets: [
{
data: [1, 7, 15, 19, 31, 40]
},
{
data: [6, 12, 18, 24, 30, 36]
}
]
};
$scope.someOptions = {
segmentStrokeWidth: 20,
segmentStrokeColor: '#000'
};
});
我黑客团队中的其他人在那天晚些时候发现了它.这是HTML:
<article class="col-xs-6 col-md-offset-3 col-md-6 center">
<canvas id="expenses" width="200" height="100"></canvas>
<script>
var pieData = [
{
value: 20,
color:"#878BB6"
},
{
value : 40,
color : "#4ACAB4"
},
{
value : 10,
color : "#FF8153"
},
{
value : 30,
color : "#FFEA88"
}
];
var pieOptions = {
segmentShowStroke : false,
animateScale : true
}
var expenses = document.getElementById("expenses").getContext("2d");
new Chart(expenses).Pie(pieData, pieOptions);
</script>
</article>
更多信息,我们的github repo(视图是"cashflow.html"),并了解它是如何呈现的.
可能不是最好的方法.
