I've been trying to change the linestyles in a LineCollection, but
without any success...
If I'm using:
col = collections.LineCollection(listXY, linewidths=circwdt,
colors=circcol, linestyle='solid', label=plabel)
it works fine, but anything other than 'solid' gives me an error when
the code calls FigureCanvasAgg.draw(self) (it is a wxpython app):

>From the MPL docs, I see that i should be able to use other linestyles:
http://matplotlib.sourceforge.net/api/collections_api.html#matplotlib.collections.LineCollection
linestyles [ ‘solid’ | ‘dashed’ | ‘dashdot’ | ‘dotted’ ]
a string or dash tuple. The dash tuple is:
I'm using MPL 0.99.0 in Ubuntu Karmic (9.10)
