[Matplotlib-users] Scatter is slow to render many points

[Gregory D. <Gre...@cn...>]

Hi all,

I'm using matplotlib inside the backend_gtkagg with the scatter function 
to draw a simple graph with 20000 to 40000 points. The points may have 
only 2 differents sizes and 4 differents color depending on some criteria 
and should be 'clickable'.

The problem is that the plot rendering is very slow when it deals with 
~10000 points, especially if we compare it with the rendering of the plot 
function using simple points (as the "data_browser.py" example)

Does anybody knows if there is a way to make things going a little 
bit faster?

Thanks,
Gregory
