If the band is too thin, band titles are unreadable.
Is there a way to show the title only if there is the minimum space to show it?

ScrollingStabilizing and ClipAreas

Hi,
in my chart I use ClipAreas to hide invalid data.
When I set x Axis scrollmode to XAxisScrollMode.Scrolling and, for all my PointLineSeries, ScrollingStabilizing = true, hidden data by ClipAreas are shown.
See the attached picture.
