Colour of a line....

Hi,

I have a problem with lines in a plot. I want to draw a horizontal dotted line and the dots should hide behind other objects in the plot. So if there is a other object the line should not be visible and afterwards it should normally go on. Is there any option I could use?

Thanks a lot!

Okay I think Erase Mode is the right one. If I use this it doesn`t work. Is there any other parameter I have to change?

Use uistack() to push the line to the bottom. Or just draw it first.

Note: if you are using the OpenGL renderer (necessary if you are using transparency), then if you have a line in the same plane as a surface, it is not possible to control the order of the drawing. The work-around in such cases is to use a 3D line with a Z value that puts it "behind" the surface at normal viewing angles.
