[Matplotlib-users] sluggish pdfs with large data sets

[Daniel S. <dan...@gm...>]

hello,

i'm using matplotlib on os x and am having issues with plots of large  
data sets.  i have some plots which contain about ~10000 points and  
the pdf files generated bring preview.app and quicklook to their knees  
when they open the pdf files.

here is a small file that reproduces my issues.  at 1000 points it is  
snappy and at 10000 it is a pig.

is there a setting to downsample or otherwise compress?

best,
drs



import matplotlib.pyplot
import scipy

x = scipy.rand(10000)
matplotlib.pyplot.plot(x)
matplotlib.pyplot.savefig('rand.pdf')
