chart.js如何使用动态数值？

Question

<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]
            }这里面的数据如何实现动态传值，如果我们的值是从数据库取得怎么传过去？
