比如说y轴需要的数据是 const data = [10,40,70,20,50,30]
那我们y轴所需要的区间是
一开始想
1.极差 const range = (70-10) / data.length =10
那y轴上每一个点的波动区间正负10

2.重组每一项数据
let res = []
for(let i=0; i<data.length; i++){
res.push(data[i]+10)
}
3.结果 [20,50,80,30,60,40]

这样一个简单的计算在y轴上上下都留了空间但是换成写其他数据比如
[15,13,22,45,47]
这些数据在坐标系上就有点错位

不知道还可以如何优化
