Hi,

I am wondering how we can edit a diagram plotted in maple. for example in editdiagram.mw I want name tips of diagram as "a", "b",.... and write them besides the tips on diagram.

Another question is how we can make color different parts of a single diagram by various colors? for example in above diagram we want make blue vertical line, make green horizontal line and make black the curve line?

Thanks a lot
