我正在制作一个图表,当单击按钮时可以使用不同的数据更新。
当x轴不改变其长度时,下面的代码似乎有效,但是当x轴长度改变并且图表更新时,我得到这个错误:Error: Invalid value for <circle> attribute cx="NaN"
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);
});
是什么导致这个错误?

这是一个明显的错误。它似乎不影响显示,它只是引发一个不想要的控制台错误:
