No, at least not currently. Tools that can do this include pdftk and
pdfTeX; in pdfTeX the easiest way to go is probably to use the
pdfpages package.

I was not aware of PyPDF, but it looks like it is being actively
developed. Perhaps you could submit a bug report to the author of
PyPDF?

IMHO modifying rcParams is not a good way to use the object-oriented
interface. It can be very useful for interactive plotting using the
(state-machine) pylab interface, but such non-explicit state can make
an object-oriented program difficult to follow. Of course rcParams is
needed for things like selecting fonts.

rcParams is initialized from the matplotlibrc file.

If you want more detailed control, I think you have to use the keyword
arguments (or set the equivalent properties on the line objects).

I think the patch.* parameters affect the markers created by
scatter().

One possibility could be to change the return value of errorbar() from
the current unstructured list of lines to e.g. a dict of lists of
lines, so you could modify them separately. Here is a patch of mine
that did this for boxplot (and was accepted):

Would something like this help with your problem?

Hello, 

I apologize if this message was already posted, it was bounced back to me.

I am having some confusion about how best to set my plot settings. Should I use rcParams, or carry around my own class object holding plot() and scatter() settings? I have a wx app and I plot simple x y data. I manually add data values and each time I do my app clears then redraw the canvas. I'm using only plot() scatter() and axhline() in my app. My problem is that my code is a bit messy because I have my own class object that stores all the selected plot settings, ie colors, line widths, etc. 

I discovered the rcParams and I thought this would really clean up my code a bit. So I could set the rcParams and not have to keep track of my plot() and scatter() settings because matplotlib already does. Several problems happened when I did this:

1) from what I read, I expected a rcParams value to keep if I closed my app then reopened it. But it went back to some default... maybe the matplotlibrc file? are these things separate? 

2) when I changed the rcParams for my line style (for example) ALL line styles changed not just the lines in plot().

3) I didn't see a rcParams object for the scatter() parameters, markers size, style, color, linewidth etc. Is this possible?

Am I using rcParams correctly? I want to take advantage of setting my plot() and scatter() settings by using matplotlib instead of having to reset them each time I draw(). 

Thanks!

Jeff
