我制作的图表可以在单击按钮时使用不同的数据进行更新。

下面的代码似乎在x轴没有改变其长度时起作用,但是当x轴长度改变并且图表更新时我得到了这个错误:Error: Invalid value for <circle> attribute cx="NaN"

代码:

var svg = dimple.newSvg("#stepContainer", 400, 300);

        var step_data = [
             {Period: 1, FIP: (Math.random() * 1000000)},
             {Period: 2, FIP: (Math.random() * 1000000)},
             {Period: 3, FIP: (Math.random() * 1000000)},
             {Period: 4, FIP: (Math.random() * 1000000)},
             ];

        var stepChart = new dimple.chart(svg, step_data);
        stepChart.setBounds(50, 40, 305, 205);
        var myAxis = stepChart.addCategoryAxis("x", "Period");
        stepChart.addMeasureAxis("y", "FIP");
        var s = stepChart.addSeries(null, dimple.plot.line);
        s.interpolation = "step";
        stepChart.draw();

        d3.select("#btn").on("click", function() {
        // If the length of the x-axis stays the same I don't get the error
        //var periods = 4;
        var periods = Math.random()* 50;
        arr = [];
        for (i=1; i <=periods; i++) {
            arr.push({Period: i, FIP: (Math.random() * 1000000)});
        }

           stepChart.data = arr;
           stepChart.draw(1000);
        });

造成此错误的原因是什么?

这是一个突出的错误。它似乎不会影响显示,它只会引发一个不需要的控制台错误:
