I want to use the SeriesSelectionModifier to select a series when I click on the line between points.

I want to use the SeriesSelectionModifier to select a series when I click on the line between points.

Using the SeriesSelectionModifier, I can select a series by clicking the mouse on the point.

However, when I click on the line between points, the SeriesSelectionModifier does not work and I cannot select a series.

How can I select a series even if I click on the line between points?
