more information on this. if i try to use pdf.use14corefonts, like was suggested by Jouni, as follows:

from scipy import *
import matplotlib
matplotlib.use('PDF')
from matplotlib import rc
import matplotlib.pyplot as plt
rc('font',**{'family':'sans-serif','sans-serif':['Helvetica']})
rc('pdf', use14corefonts=True)

then when i open the generated pdf in adobe illustrator i get the error: "The font "Helvetica-Narrow" contains a bad /BBox."  -- then no labels are shown in the graph, only the nontextual elements.

hi all,

I am not sure if I have helvetica installed as a TTF -- how can i install it if i don't?

i followed the debug suggestion and here are the results. when i set the font to arial, using:

from matplotlib import rc

rc('font',**{'family':'sans-serif','sans-serif':['Helvetica']})

then the relevant output i get using --verbose-debug is:

any idea what might be wrong here?

Are you certain you have Helvetica installed as a TrueType font?  If you don't, the only way to get the Postscript Helvetica is to set "ps.useafm" to True.

I just wanted to add: if i simply set the font to Arial, using

rc('font',**{'family':'sans-serif','sans-serif':['Arial']})

then it works. But the same call with Helvetica still defaults to that Bitstream/default font of matplotlib. any idea why this might be? could matplotlib be confusing helvetica with bitstream?

   hi,

   i am trying to use the Helvetica font on matplotlib. i am using
   mac os x (so i definitely have helvetica installed) with version
   0.98.5.2 of matplotlib. my code is:

   from scipy import *
   import matplotlib
   matplotlib.use('PDF')
   from matplotlib import rc
   import matplotlib.pyplot as plt
   rc('font',**{'family':'sans-serif','sans-serif':['Helvetica']})
   plt.hist(rand(100))
   xlabel(r"My x axis $\alpha$")
   ylabel(r"My y axis $\beta$")

   i verified that plt.rcParams gets modified to use 'Helvetica' as
   the value for font.family, etc. but i still get the default font
   used in all of these figures. i tried using the PS backend using
   matplotlib.use('PS') but the problem persists. i am interested in
   getting out PDFs that use helvetica everywhere.

   does anyone know how to fix this? thank you.
