Is there a standard way to add fixed-size, arbitrary-design symbols to axes?
- Their position must be given in data coordinates
- Their size must be given in physical coordinates (inches/points)
They basically need to behave like plot markers, but with the ability to specifiy arbitrary designs.
e.g. See http://commons.wikimedia.org/wiki/File:Cloud_cover_3.svg for an example symbol.
Currently I'm defining my symbols using a sequence of Patch objects, and then using PatchCollection (with its offsets and transOffset properties, and its set_transform() method) to do the positioning/scaling.
Is there a better way?
Any suggestions gratefully received!
