Scatter plots with lots of values close to each other are not displayed

[jamespinkerton]

Hi,

When I make a scatter plot in matplotlib, sometimes it renders and sometimes it doesn't. When I clip values (-1, 1) it fails, but when I clip to (-5, 5) I get to see the plot. I can't figure out why this is. When I savefig, everything works no matter what.

Thank you so much for this repo. It is amazing!
