[feature] linear 维度支持跳过指定区域 #2712

• I have searched the issues of this repository and believe that this is not a duplicate.

What problem does this feature solve?

减少了多折线（复用Y轴）图中无用的空白区域面积，例如下图的橙色部分

What does the proposed API look like?

{
  type: 'linear',
  skip: value => value >=80 && value< 100
}
