I need to save figures with many data (10.000 points per figure or more...) in lower resolution, to open them with the pdf viewer more quickly. I've heard that a proper combination of rasterized = True and dpi should be used in pylab.savefig.
What are these arguments? others may be used within savefig for this purpose? Please give a clear example
PD: I have PYTHON 2.7
After ploting or when you get the axis available:
pylab.gca().set_rasterized(True)
or for every axis ax you know
ax.set_rasterized(True)
Finally
pylab.savefig(file_name, dpi=your_choice)
where dpi could be 80, 160, 300, 600, etc.
