Re: [Matplotlib-users] Switching between different font settings

Thank you for your answer! I am trying to use helvetica and yes, text(r'$1+2+3={}$1+2+3') gives me helvetica for the non math mode case. But how do I get math mode to use the same font? I've tried to set 'mathtext.rm': 'sans-serif' in my params dict and then run "rcParams.update(params)" but that d

Hi, the code given works for me in principle. If I run ipython without the -pylab flag and do an import * from pylab at the start instead, I can run this code and it runs fine. (If not, the plot() will imply the show and everything after that doesn't matter any more.) However, I'm now running in

I can't reproduce the error and I guess it is back end specific. Anyhow, the fontproperties object were created incorrectly and this may be cause of the problem. I just thought your original dictionary was in a correct form. So, test your code w/o fontproperties and see if your text is placed in a

I guess you're missing vertical and horizontal alignment. Also, your font properties were not set correctly. The 4th argument of the text function is a color. fontdict2 = {'fontweight':'light', 'color': 'r', 'fontsize':fontsize} fp = FontProperties(fontdict2) labels = p
