雷达图，始终以最小点为基点

Question

我使用了雷达图 只有一个数据，但是始终将最小点用作基点，如何将其更改为0作为基点？

我的代码，“ 2”被视为图表上的最小值...

{
    backgroundColor: "rgba(179,181,198,0.2)",
    borderColor: "rgba(179,181,198,1)",
    pointBackgroundColor: "rgba(179,181,198,1)",
    pointBorderColor: "#fff",
    pointHoverBackgroundColor: "#fff",
    pointHoverBorderColor: "rgba(179,181,198,1)",
    data: [5, 5, 3, 2, 4, 5]

},
