Chart.js，设置最大值 [英] Chart.js, set a max value

问题描述

我用 Chart.js 制作一张雷达图，但它只有最大的值。我想将它设置为标准的最大值，所以范围是0到100，你可以看到你的进度是如何在不同的主题。有没有人知道如何使用 Chart.js 来设置雷达图的最大值范围？

I am making a radar chart with Chart.js, but it only gets as big as the biggest value that's in it. I want it to be set to a standard max value, so the range is 0 to 100, and you can see how your progress is on different topics. Does anyone know how to set a max range of value to the radar chart with Chart.js?

（我试图添加一个额外的数据集，设置为100，使它不可见，但是你看到的数据，如果你悬停在雷达的点，

(I tried just adding an extra dataset that's set to 100 and making it invisible, but than you see that data if you hover over the points in the radar, so that doesn't really look right)

推荐答案

您可以使用scaleOverride来执行此操作，例如

You can use the scaleOverride to do this, like so

...
var myChart = new Chart(ctx).Radar(data, {
    scaleOverride: true,
    scaleSteps: 5,
    scaleStepWidth: 20,
    scaleStartValue: 0,
});
