I found something strange inside the eps file create with matplotlib. I
used matplotlib to trace a port of a spectra (I used the
function plot and axis). I have been very surprise to see that all the
spectra was inside the eps file. To see it, I must admit that I did
something weird. I create an eps file with matplotlib and I transform
the file in svg format with pstoedit and I edit this file with inkscape.
I don't know where is the problem but I don't think that it's necessary
to have all the point inside the output file, perhaps it's not possible
to do anything to change it but that can create some huge file. So if
nothing can be done, that will be a good idea to put it in the FAQ to
let the users cut their data if needed.
