您可以制作多个数据集。一个用于2004年,一个用于2014年。 有一个示例代码:http://www.chartjs.org/docs/
var data = {
labels: ["Eating", "Drinking", "Sleeping", "Designing", "Coding", "Cycling", "Running"],
datasets: [
{
label: "My First dataset",
backgroundColor: "rgba(179,181,198,0.2)",
borderColor: "rgba(179,181,198,1)",
pointBackgroundColor: "rgba(179,181,198,1)",
pointBorderColor: "#fff",
pointHoverBackgroundColor: "#fff",
pointHoverBorderColor: "rgba(179,181,198,1)",
data: [65, 59, 90, 81, 56, 55, 40]
},
{
label: "My Second dataset",
backgroundColor: "rgba(255,99,132,0.2)",
borderColor: "rgba(255,99,132,1)",
pointBackgroundColor: "rgba(255,99,132,1)",
pointBorderColor: "#fff",
pointHoverBackgroundColor: "#fff",
pointHoverBorderColor: "rgba(255,99,132,1)",
data: [28, 48, 40, 19, 96, 27, 100]
}
]
};
我已经做了同样的事情,但我现在无法发布截图。
