[matplotlib-devel] Size of scatter markers

[Matt W. <ma...@ma...>]

I want to calculate the intersection of the edge of a marker with a line
running from the center to another marker. I want to do this in order to
decorate the intersection.


I'm using the following code(derived from some code in axes.py) to try
and "divine" the size:

        node_sz=sqrt(size*(ax.figure.dpi.get()/72.0))

This is not right. Clearly, I just don't have an idea what I'm doing
(when it comes to calculating the distance along a vector(the along a
vector part is easy) of the size of scatter marker). Anyway, who can
point me in the right direction would be my hero for atleast 2 or 3
hours.
