Thanks again. I didn't know it was complete :) For the second idea you mean something as generic as plotting such markers? plt.plot(range(10), linestyle='None', marker=u'※ ') On Fri, Feb 26, 2010 at 2:56 PM, Michael Droettboom <md...@st...> wrote: > SVN trunk has support for mathtext as symbol markers -- > > plot(range(10), linestyle='None', marker=r'$\clubsuit$') > > We could support arbitrary (non-math) text, too, fairly easily.
