Re: [Matplotlib-users] savefig as pdf not generating vector graphics?

Matplotlib's usual mathtext engine is pretty good and doesn't require any external programs. The problem is that myfig.pdf for some reason renders the figure's x and y labels as *images* rather than vector graphics. Could you send the resulting pdf file to me off-list? -- Jouni K.

you're right, i don't need to use usetex -- i removed it, but the problem
still persists. here is the pdf that it generates (code below). any idea
what is happening here? thanks very much for your help.
The file you sent was not generated by the pdf backend but by Mac OS X
10.5.6 Quartz PDFContext, which probably means that the OS X backend
saves pdf files using the OS X machinery and not the pdf backend. Indeed
the formulas look like bitmaps.
from scipy import *
import matplotlib.pyplot as plt
from matplotlib import rc
rc('font',**{'family':'sans-serif','sans-serif':['Helvetica']})
import matplotlib
matplotlib.use('PDF')
You are trying to use the pdf backend, but the last line quoted above
has no effect because you have already imported pyplot, which causes the
backend to be set as directed by your matplotlibrc file. Any call to
matplotlib.use needs to be done before you import pyplot.

[Matplotlib-users] setting figure font to helvetica
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.rcParams['font.family'] = 'Helvetica'
plt.hist(rand(100))
xlabel(rMy x axis $\alpha$)
ylabel(rMy 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.

Re: [Matplotlib-users] setting figure font to helvetica
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?

Re: [Matplotlib-users] Stopping Legend From Overlapping the Graph
Awesome, thanks. That works perfectly. Chris On Sun, Jun 28, 2009 at 12:16 AM, Jae-Joon Leelee.j.j...@gmail.com wrote: sorry. As guillaume has mentioned, you need to install mpl from svn. Here is some workaround you can try. I guess it would work with 0.98.5.3. Basically, you create a separate axes for a legend. ax1 = axes([0.1, 0.2,0.8, 0.7]) p1, = ax1.plot([1,2,3]) p2, = ax1.plot([3,2,1]) ax2 = axes([0.1, 0.1, 0.8, 0.01], frameon=False) ax2.xaxis.set_visible(False) ax2.yaxis.set_visible(False) l = ax2.legend([p1, p2], [Legend1, Legend2], mode=expand, ncol=2, borderaxespad=0.) -JJ On Sat, Jun 27, 2009 at 6:00 PM, Chris Spencerchriss...@gmail.com wrote: Thanks.

Try something like bbox_to_anchor=(0., -0.1, 1., -0.1), loc=1 Make sure to adjust the suplot parameter (or axes location) to make enough room for the legend. -JJ On Thu, Jun 25, 2009 at 9:22 PM, Chris Spencerchriss...@gmail.com wrote: How do you show the legend below the graph, so it doesn't overlap at all with the graph? The docs for the legend() loc parameter only seem to specify where *on* the graph you want it to show, which is driving me nuts because even using best, it usually hides some of my data. I want to see *all* of my graph, as well as the legend. Is there any way to do this with pylab? Any help is appreciated.

So the problem should go away if you use matplotlib from SVN. The Mac OS X backend itself can actually be fixed to use vector graphics on screen instead of bitmaps. That will need some time, but I'll get round to it one of these weeks. --Michiel. -- ___ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users
