Question

用过chart.js吗？怎么给里面的数组动态的传值？

<script>

var lineChartData = {
labels : ["January","February","March","April","May","June","July"],
datasets : [
{
fillColor : "rgba(220,220,220,0.5)",
strokeColor : "rgba(220,220,220,1)",
pointColor : "rgba(220,220,220,1)",
pointStrokeColor : "#fff",
data : [65,59,90,81,56,55,40]
}

Answer 1

将： ["January","February","March","April","May","June","July"]和 [65,59,90,81,56,55,40]作为参数传值就行了，比方说：两个都可以在后台用一个公共变量存储起来，然后赋值就行了，
你应该是想画曲线图或者是圆饼图吧，我就是这样的，或者使用ajax来加载数据也行，不过原理是一样的
