[Matplotlib-users] what decides which lines go on top of the rest

[Valentino G. <vgg...@uc...>]

I am trying to make a scatter plot (it is important that it is a scatter 
plot because I want the markers to be color coded).  Each point also has 
errobars associated and since there is no way to plot errorbars on 
scatter plots I am plotting them separately, i.e. plot twice: once with 
the errorbars and no markers and then with only markers as in a scatter 
plot. 
The problem is that regardless of the order in which I do this, the 
errorbars are alwas on top of the markers of the scatter plot and I 
would like the opposite, markers on top of the errorbars.  Can  this be 
done? And more generally, how can I choose what goes on top of what?

Thanks,
Valentino.-
