matplotlib-users Mailing List for matplotlib

Hello users,

I wish to repeatedly re-plot labels and contour data on a figure since 
redrawing the figure is temporally expensive.  The attached script (I 
apologize for its length), hopefully, illustrates a simplified version 
of what I'm trying to do -- contour temporally-varying data on a map 
projection.

I do not understand how to erase the plot label each time the figure is 
to be reused.  I also do not know how to erase the contour-fill 
although, based on the generated PNG files,  it does not, for unknown 
reasons , appear to be necessary.  From some postings, it seems that I 
have to employ collections attributes, but I have not been able to find 
documentation or examples that illustrate this.

My system:

    * matplotlib.__version__: '0.91.2'
    * sys.version: '2.5.1 (r251:54863, Apr 18 2007, 08:51:08) [MSC
      v.1310 32 bit (Intel)]'


Thanks,
-- jv

Hello,
for me it works:

Type "copyright", "credits" or "license" for more information.

IPython 0.8.1 -- An enhanced Interactive Python.
?       -> Introduction to IPython's features.
%magic  -> Information about IPython's 'magic' % functions.
help    -> Python's own help system.
object? -> Details about 'object'. ?object also works, ?? prints more.

   Welcome to pylab, a matplotlib-based Python environment.
   For more information, type 'help(pylab)'.

I would suggest to reinstall the necessary packages.

Kind regards,

Hi people

I'm trying to use matplotlib, ipython and xubuntu(gusty) all together. 
Whenever I try to run ipython with -pylab tab, nothing extra happens to 
the start up screen and pylab hasn't been imported. I have managed to 
sucessfull install ipython and matplotlib on a Redhat system and ipython 
  -pylab works. ipython and matplotlib work btw

I've tried install from source, apt and easy_install all to to avail

Can anyone suggest what I am doing wrong or an output to post to show 
more details of what is happening on my machine

Thanks

Andy

fig = pylab.figure(figsize=(6,10), dpi=96)
[...]
pylab.savefig("filename.eps", dpi=96)

,where figsize in the figure size in inches.

xylims = (-10,10) # set your axis limits here
pylab.gca().set_xlim(xylims)
pylab.gca().set_ylim(xylims)
pylab.gca().set_aspect('equal')

That's the quick-and-easy way. If the limits differ, you can create your 
own new axes instance, have a look at axes_demo.py in the examples.
