I noticed a strange behaviour :
1. I reduce a vertical axis by setting its startPosition to 50
2. I add the "Axis Arrows" tool and move the serie to the top of the chart, meaning the serie is upper than the top of the axis
3. I add a cursorTool linked to this serie, with the property Snap = true
=> the cursor will not follow the serie because of the limit set by the top of the axis
Illustration :

This is not really a "bug", but I think it's not really the expected behaviour. Is there a simple way to avoid this problem and make the cursor follow the serie even if the axis is reduced ?
