Re: [Matplotlib-users] Arrow with a dashed line

2012-03-26 Thread Jae-Joon Lee
Just to clarify, both arrowstyle='simple' and arrowstyle='-|>' draw arrows as patches. In your first example with arrowstyle='simple', the arrow is drawn as filled patch without edges, i.e., linestyle is not effective. arrowstyle="-|>" also uses a patch but no "fill", only "stroke". Regards, -JJ

Re: [Matplotlib-users] move legend to the foreground: how to use set_zorder() correctly?

zorders are only meaningful among objects in a same axes. An easy workaround is to move the legend in ax1 to ax2. ax2.add_artist(leg1) ax1.legend = None Regards, -JJ On Thu, Mar 22, 2012 at 10:13 PM, David Verelst wrote: > Hi All, > > I am plotting on two different y-axes: one on the
