How to rasterize large scatter plots?

Hi, is there an option to rasterize scatter plot? Something like rasterized=True in matplotlib: https://brushingupscience.com/2017/05/09/vector-and-raster-in-one-with-matplotlib/

For reference, I’m currently writing PDF’s with ~ 500MB size per figure…

You can drop into matplotlib to do it.

from plotnine import *
from plotnine.data import mtcars

p = (ggplot(mtcars, aes('wt', 'mpg'))
     + geom_point()
     + geom_smooth()
)

# Get figure and access the points to be rasterized
fig = p.draw()
points = fig.axes[0].collections[0]
points.set_rasterized(True)
fig.savefig('raster_points.pdf')
