Great, setting the DEPTH_WRITE_DISABLE in the model object worked.
thank you

OK, try setting the keyword DEPTH_WRITE_DISABLE either in
your view object (which your contour and line plot inherit),
or in both your contour and line plot objects. With depth
disabled, the order should depend on the order in which they
are drawn.
Cheers,
David

Ok, here goes, I place both my contour and line plot objects into a
object model which i then place into a view object
plotModel->Add,contour
plotModel->Add,line_plot
plot_view->Add,plotModel (where plot_view is a view object)
This is then displayed in my draw widget. I need the line plot to
display over the top of top contour.
thanks
Clive
