Hi,
Is there a simple way to draw a range on x axis with mouse and display an annotation with the value of the selected range?
Is possible to add markers where the range edges intersect the series too?

Thank you

To draw a range, use a Band. In band.ValuesChanged event handler, update the annotation.

To put markers on the range edges, again use the band.ValuesChanged event handler and use pointLineSeries.SolveNearestDataPointByValue and set that to marker's X value.

Something like that...
