[Matplotlib-users] Coloured background regions?

[Robert L. <ro...@le...>]

I have a requirement to generate a scatter plot with the background divided into 
4 equal rectangular regions, each a different colour/shade indicating a 
particular characteristic of the points in that region. What is the best way to 
do this in matplotlib?

PS I apologise in advance if this is answered in the user guide, but I'm unable 
to download it atm for some strange reason.
