matplotlib-users Mailing List for matplotlib

Hello, I have the following function as an example. You can see I started to
play with one of the demos to put a colorbar on it. I'm a little confused
how to make this work, as on my figure I have several 'collections'. The
other examples I have seen deal with one collection. Maybe someone could
show how to make a color bar here??
Thanks!

You're right, I had just tried something similar before I received your post:
I modified the setup.cfg with:
#gtk = False
#gtkagg = False
tkagg = True
wxagg = True
macosx = auto
qtagg = True

-->  I'm not sure if the qtagg means anything, but since I'm using qt, I thought I'd throw it in there and see what happens.

Thanks for the help!

Kurt:

I don't think you should be building the macosx backend on linux.  Try 
copying setup.cfg.template to setup.cfg, then edit that file and 
uncomment the line

#macosx = False

Then run setup.py build again.

Is it possible I need a special version of g++?
Kurt


 		 	   		  

okay. don't shoot me

you need to start ipython with:

   ipython -pylab

as noted in: http://matplotlib.sourceforge.net/users/shell.html

made someone else can benefit from my mistake

sorry for bothering you

That's exactly what happens in ipython (in pylab mode), if you don't 
call show.

But you need /usr/include/tcl8.5/tk.h.  Matplotlib is detecting a tk 8.5 
installation, so it's looking for a tk 8.5 header.

but i want to:
 1) plot something
 2) go on in ipython (with the figure/plot staying on)

is that really not possible?

The king who needs to remind his people of his rank, is no king.

To gain that which is worth having, it may be necessary to lose everything else.

Well, while I waited for more help/thoughts on the matter, I happened to have another machine with Jaunty 9.04 that I thought I'd give a try
 I consolidated the install down with the "apt-get" commands at the bottom, and matplotlib failed on the new machine as well (but took longer to fail possibly because the other machine had already compiled everything up to the failing point).  This "new" machine is Intel-based, whereas the other one was AMD-based.  Similar error message:

Greetings.

What i want to do is something like:

ipython ...

----

t=linspace(0,2,50)
y=sin(2*pi*t)

pyplot.plot(t,y)
pyplot.show()

----

I get the plot here ... but now i want to do some more stuff in
the ipython shell (and possibly have the plot still open)

How do i free the shell from the plot thread?

Thanks

To gain that which is worth having, it may be necessary to lose everything else.

Jeff,
   I had already had tk-dev installed:
$ sudo apt-get install tk-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
tk-dev is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded

Please see my latest...  This is amazingly difficult.  Didn't remember it being this hard when I did it on my Suse machine.

Getting closer...  I'm going to post the sum total of "apt-get installs"  I had to do to get matplotlib installed when I get it working (prelim. is at the end of this message).

I'm thinking on this one, something with ltk in it, but none of these look promising:
[code]
apt-cache search tk | grep "ltk"
fltk1.1-games - Fast Light Toolkit - example games: checkers, sudoku
freepops-updater-fltk - Graphical interface for the freepops updater engine
hfsutils-tcltk - Tcl/Tk interfaces for reading and writing Macintosh volumes
libtcltk-ruby - Tcl/Tk interface for Ruby
sufary-tcltk - Tcl/Tk interface for SUFARY
mgltools-opengltk - opengltk python extension
fltk1.1-doc - Fast Light Toolkit - documentation
libfltk1.1 - Fast Light Toolkit - shared libraries
libfltk1.1-dbg - Fast Light Toolkit - shared libraries with debugging symbols
libfltk1.1-dev - Fast Light Toolkit - development files
libtcltk-ruby1.8 - Tcl/Tk interface for Ruby 1.8
libtcltk-ruby1.9 - Tcl/Tk interface for Ruby 1.9
[/code]

Here's what's in my /usr/lib (for libtk8.5*) directory:
[code]
$ ls /usr/lib/libtk8.5*
/usr/lib/libtk8.5.so.0

Here's what I "had" to install so far for Kubuntu Jaunty 9.04 (first few were required by numpy):

  495  sudo apt-get install matplotlib  <-- always worth a try... didn't work

  520  sudo apt-get install libatlas3gf-3dnow

  523  sudo apt-get install libblas-dev

  532  sudo apt-get install gfortran

  534  sudo apt-get install lapack

  536  sudo apt-get install liblapack-dev

  537  sudo apt-get install python-symeig libatlas-3dnow-dev

  549  sudo apt-get install freetype

  552  sudo apt-get install libfreetype6

  554  sudo apt-get install libfreetype6-dev

  555  sudo apt-get install tk

  556  sudo apt-get install dvipng

  569  sudo apt-get install python-qt4 python-qt4-common

  574  sudo apt-get install python-tk wxPython

  576  sudo apt-get install python-tk python-wxaddons

  577  sudo apt-get install python-tk python-wxtools

  590  sudo apt-get install wx-common

  593  sudo apt-get install libwxbase2.8-0

  594  sudo apt-get install libwxgtk2.8-0

  603  sudo apt-get install tcl8.5-dev


Someone may want to update the install page once I get a completed list.

Hey, coparing on how GTK2 example is done I've seen a difference between the two!

In QT4Agg example and WX example the code use:

canvas.copy_from_bbox(ax.bbox)
replacing all occurrence of ax.bbox with ax.get_figure().bbox solved all the issue I add.

Perhaps we should correct the examples.
I can send you the good working example if you want.

Cheers,
Laurent

I've just installer GTK on windows + tested your file and it works...
Moreover, I've modified the source to make the code use QT4Agg instead of GTK and the bug does not appears.
So I think it is more an issue of misusing bliting technique in other examples.
(still your gtk example is more beautiful but 10 times slower than other examples, so is blitting really working in this case ?)

I'll dig this a little more but any idea welcome :)

What does

Kurt:  It's not finding tk.h, so you probably need to install the tk-dev package.

I'm pretty sure I have all the required minimal dependencies installed, but get an error when I sudo python setup.py build.  Any thoughts?  I can start python and import Tkinter without an error.  So I don't know why it's not finding it.

I've not been able to find a successful way to install matplotlib since
upgrading to OS 10.6. There doesn't seem to be an egg for it. Easy_install
matplotlib finds an old version (0.91) that is not compatible with the new
numpy supplied by Apple. Easy_install matplotlib-0.99.1 can't find it.
Likewise, easy_install
http://sourceforge.net/projects/matplotlib/matplotlib-0.99.1/matplotlib-0.99
.1.1.tar.gz doesn't find it.

I tried downloading the gzipped tar file, then python setup install , but I
got a compile error. I'm now stumped. Any ideas?

Thanks,
Bill Carithers

Hello,

I've tested so far with wx and QT4 backend.
The two are buggy.
Easy way to reproduce the bug (another way I mean)

ax = p.subplot(212)
ax2 = p.subplot(211)

and the two backends got the same error.

Note that I'm under windows. I'll try under linux tonight just to check.
I'll also try gtk backend as you suggest.

Update in next email :)

I haven't tested it with qt4, but with gtk, add_axes DOES work.

So, can you try other backends and see if they work?

And, I believe that add_subplot -> add_axes is a only change you made?

Unless the problem is persistent among other backends, I hope other
developers who use qt4 backend step in and help.

I personally think it is best to use major ticks with labels and minor
ticks w/o labels.

If you need more than that, consider using a custom tick formatter.
