duplicate of #18268 , #18948 and others ... first reported in 2017 in #5801
Related to series.type:'line', type:'bar' works fine.

@helgasoft Thanks for the help. This issue seems to be a different one with #18268 and #18948 because this one is about the blurring of the junction area and the others are when there is only one inRange. I tried to fix this issue but failed to do so. As discussed in #15711, this problem is caused because we use gradient to implement visualMap pieces. If someone is interested in fixing it, the related logic is in LineView.ts#getVisualGradient and PiecewiseModel.ts#getVisualMeta .
