Thank you very much for the reply...but actually there are many points in my plot out of which for some of them I want to display their labels (which may be sometimes big) probably vertically and in some way so that they superimpose the least (of course without changing the point coordinates).Is there any module that can do this or can I use the canvas to show points with labels vertically (as my points would be on the outer edge of a circle and I want the labels for the points on the circle to be displayed in the graph)..
