I drawn a Line series using Syncfusion MAUI chart.
In this when I clicked on the series , It was considered as first click
Again I clicked , that was second click

我用SyncFusion毛伊图画了一个线列。在这个我点击这个系列的时候，它被认为是第一次点击，那就是第二次点击

I want to highlight series in between the two clicked points.

我想突出显示两个单击点之间的系列。
