Re: [Matplotlib-users] clearing a figure
Belinda - The hold state is on by default when you use pylab. To clear a figure you use clf(). Here's a brief example: from pylab import * figure() # Not really needed, you could have typed plot right away, but here you can set some nice features like the size plot([1,2,3]) plot([2,1,2]) # Will appear on same figure clf() # Clears entire figure (back to what you had with figure() ) Mark Message: 10 Date: Tue, 09 Jan 2007 19:50:15 -0800 From: belinda thom [EMAIL PROTECTED] Subject: [Matplotlib-users] clearing a figure To: matplotlib-users matplotlib-users@lists.sourceforge.net Message-ID: [EMAIL PROTECTED] Content-Type: text/plain; charset=US-ASCII; delsp=yes; format=flowed Hello, I'm a new matplotlib user, coming from the Matlab end.

(The nice thing belinda about IDLE is its fresh state each time you run a file; belinda this goes away when -n is used). From http://matplotlib.sourceforge.net/backends.html#TkAgg Tkinter GUI backend Todd Miller has written a backend for Tkinter that uses the agg backend for rendering. To use Tkagg, you need to set the BUILD_TKAGG flag in setup.py. The windows installer comes with TkAgg prebuilt. See agg backend for more information on agg rendering and fonts.

I also looked into SciTE a little and discovered that it is related to Scintilla which in turn was derived from Pythonwin. scintilla This indicates to me that the same problem with Tkinter may be affecting both (SciTE and Pythonwin)... but I am out on a limb.

Re: [Matplotlib-users] idle and ipython and axis
Mark, BTW, when you use pylab in interactive mode, the axis() command should scale your figure interactively, also under IDLE. Have you tried that? Yes, I tried using axis in both IDLE and IPython. IPython's redrew the axis automatically whereas IDLE's did not. I am not sure, but I think this difference in behavior is b/c IPython is a bit better about calling draw_if_interactive after most pylab functions (see Eric Firing's http://www.mail-archive.com/matplotlib- [EMAIL PROTECTED]/msg02037.html) than IDLE is. I have experienced the same problem with IDLE. It only works with -n, but then you lose the nice feature of 'starting over'. Does anybody know a fix so we can do both? I too would LOVE to have the ability to start over as IDLE w/o the -n allows. Unfortunately for me (on a Mac) I've not yet been unable to use WxAgg w/matplotlib using Mac-available packages.

Re: [Matplotlib-users] installing numpy, matplotlib, scipy from source on a Mac
I am posting this message to both numpy and matplotlib mailing lists because the thread relates to both. First, Robert Kern kindly provided step-by-step instructions for Macs (PPCs and Intels) regarding how to install FROM SOURCE the packages needed to allow Python to become a viable alternative for Matlab. Details regarding the installation of matplotlib (along with wx, which is supposed to allow the WxAgg backend to work), numpy, and scipy were provided. The reason for installing FROM SOURCE on a Mac is because various packages need to be compiled in such a way that they rely on the same underling shared libraries, etc. for things to work (I've described some problems w/installing from numpy, scipy, and matplotlib dmgs at http://www.mail-archive.com/ numpy-discussion at scipy.org/ msg00481.html). From these instructions, I've been able to acheive numpy.test() anad scipy.test() that run w/no failures -- hooray! However, after installing wx and matplotlib, various problems result: 1) warnings about fonts 2) wx fails to work I've appended the warnings below. These only occur the first time pylab is imported (does this make sense?). After that, I've appended the issues I've had when trying to use wx as a backend. One reason I'd like to be able to use wx is that it appears with TkAgg, running IDLE (w/the -n flag) can hang (see: http://www.mail-archive.com/matplotlib-users@lists.sourceforge.net/ msg02039.html). Point that originally confused me: although wx is needed for the WxAgg backend, you don't need to install the analogous Tk package to use TkAgg PROVIDED you're using MacPython, for that comes bundled w/ an Aqua-based Tk interface. I'm on a G4 PPC, w/OS X 10.4.8, and using MacPython 2.4. Any idea what wx doesn't work?
