Re: [Matplotlib-users] Millions of data points saved to pdf

[Alan G I. <ala...@gm...>]

Suppose each data point is only 1 point (1/72 ") in diameter.
A solid line across a 20" page is less than 1500 points.
You're using a fraction of a page per graph and trying to
plot 5,000-15,000 points per graph.  This is pointless (pun
intended) for visual display, especially since you do not
care about the individual points.  What happens if you
decimate the points?  Is the result acceptable?

Perhaps you could do even better than that, given your
posted description.  Fit a line to the points, and only
plot the fitted line.  Or use something like `hexbin`.
