这是因为,构建图表的方式不正确(Chart.js 1.x的 。
以下是在Chart.js 2.x中创建图表的正确/正确方法:
$(document).ready(function() {
loadDonutChart();
});
function loadDonutChart() {
var ctx = document.getElementById("MydonutChart").getContext("2d");
var data = {
datasets: [{
data: [30, 50, 100, 40, 120],
backgroundColor: ["#F7464A", "#E2EAE9", "#D4CCC5", "#949FB1", "#4D5360"]
}]
};
var options = {
animation: {
easing: 'easeInOutQuart',
duration: 1000
}
};
var myPieChart = new Chart(ctx, {
type: 'pie',
data: data,
options: options
});
}

首先,您的数据变量是错误的。 在文档中,我没有找到任何可以使用对象数组的信息。 数据必须是一个对象!
这是你的,这是错的:
var data = [{
value: 30,
color: "#F7464A"
}, {
value: 50,
color: "#E2EAE9"
}, {
value: 100,
color: "#D4CCC5"
}, {
value: 40,
color: "#949FB1"
}, {
value: 120,
color: "#4D5360"
}];
或许看一下这个例子:http://www.chartjs.org/docs/latest/getting-started/usage.html
