Hi,

I am using qwt 6.1-rc3 and what i want to is add some little moveable arrows to a qwtplot on the axis scale widget (?) but not on the plot canvas (see picture).

How can i achieve this?

Thanks

Derive from QwtScaleDraw ( for drawing of the arrow ) and install en event filter for the axis widget, where you handle the mouse events.
