Re: [Matplotlib-users] Change colorbar orientation once drawn
Try
cb.orientation = "horizontal"
cb.update_bruteforce(cb.mappable)
it seems to work okay.
However, note that "update_bruteforce" clears the axes then redraws.
So, if you added some artists in the colorbar axes by yourself
(although this is not likely), they will be lost.

Yeah, my e-mail client (gmail) chooses for e-mail from the matplotlib-users list as default recipient of the answer always the sender (maybe a misconfiguration?).

All you tried won't work, diagram_cl is not included with matplotlib, and as I think it never will. Please clone or download from http://github.com/friedrichromstedt/diagram_cl .

Ah, ok, not right now (perhaps later): for the purpose of adding your code to the numpy bug ticket, I think it's best if I use something a little more ubiquitous. ;-) But it looks useful, so I'll probably grab it and try it out myself; is it pure python, i.e., should I be able to just put it in a folder containing an init file in site-packages and then it should "just work"?

Yeah, simply have a look at diagram.py And yes, it should work out-of-the-box. The init file should be already included. Simply put it in a folder. It's tiny. Everything needed should be: import matplotlib.figure fig = matplotlib.figure.Figure() ax = fig.add_axes((0.2, 0.2, 0.6, 0.6)) ax.imshow(...) And would you mind if I put my opinion about the not-a-numpy-issue character on the numpy list too? I think it's a pure matplotlib problem, in my opinion numpy is behaving well, although they told you to fill in a ticket?

[Matplotlib-users] Fixing Figure Size
hello,
I am working in Python with TkAgg. I have several plots that I would
like to display on a single figure. The problem is, when I set the
figure size to 12in wide, 6in high (which is perfect for my laptop) the
plots get scrunched up. If I resize the window in which they're
displayed then the plots scrunch up even further. So it appears to me
that the figure size is tied to the window size.
I would like to set the size of the initial window in which the plots
appear and then fix the size of the canvas? frame? figure? (not sure
what I need to fix). I have created a scrollbar on the window to permit
scrolling up and down.
I have attached the Navigation Toolbar to the bottom of the window,
which is where I would like it to stay. So, the plots should scroll up
and down with the toolbar fixed.
My small sample program is attached.
I am using Tk (as opposed to another GUI) as I am generating these plots
from data in SimPy and am using SimGUI to control the model execution
and plotting.
I would greatly appreciate any help!
Regards,
Bonnie Douglas
