Re: [Matplotlib-users] How to control space between ylabel and yaxis (Was: how to control space between ylabel and yticklabel?)
Fri, 21 Sep 2007 09:53:52 +0200, Mark Bakker [EMAIL PROTECTED]: I think LABELPAD is the padding between the label and the tick. I did not think about it. Probably you are correct. Yet it still helps if you have big/multiline axis label. What I would like to control is the distance between the label and the y-axis itself. This is desired when you do multiple subplots and you want all ylabels to align nicely; they may differ depending on the numbers along the yticks. Well, I see the problem. One solution is to use custom Formatter for yticks/xticks (e.g. FixedFormatter or FormatStrFormatter) to ensure that tick labels have the same width/height (printed with the same precision or padded with spaces). User's Guide explains how to use formatters. - This SF.net email is sponsored by: Microsoft Defy all challenges.

[Matplotlib-users] error in ax.bar
Hello list, with the latest version of svn the pylab.hist command doesn't work if I use align='center'. The error is due to a problem in the ax.bar - function as you can see in the example below. Probably width should be an array and not a list if one want to build width/2.. I'm not sure what is the right solution, but I have two proposals: - change line 3187 to left = left - npy.asarray(width)/2.0 - uncomment lines 3123-3126 in axes.py, but I don't know what will be destroyed by that thanks in advance for any help, best regards Matthias example - code : In [1]: from numpy import ones, arange In [2]: from pylab import axes In [3]: ax = axes() In [4]: ax.bar(arange(10), ones(10), width=0.8, bottom=None, align='center') --- exceptions.TypeError Traceback (most recent call last) /home/michler/ipython console /scratch/michler/SOFT/lib/python2.4/site-packages/matplotlib/axes.py in bar(self, left, height, width, bottom, color, edgecolor, linewidth, yerr, xerr, ecolor, capsize, align, orientation, log, **kwargs) 3185 elif align == 'center': 3186 if orientation == 'vertical': - 3187 left = left - width/2. 3188 elif orientation == 'horizontal': 3189 bottom = bottom-height/2.

Re: [Matplotlib-users] latex labels on saved plots
Do you have ghostscript installed? If you set verbose.level to debug or
debug-annoying, what do you get?
I realized that the ghostscript path wasn't set up properly, so that was
what was causing part of the problem with EPS files. It works sometimes
now (sometimes the EPS is just a blank file, even though the plot shows
up properly when I do pylab.show(). I'm still trying to narrow down
what ameks the difference here).
I guess I mean TeX-like mathtext format parsed by matplotlib. For
example, I'm using things like this:
rc('text', usetex=True)
Plotting.xlabel(r'\textbf{Time (s)}', fontsize=16)
usetex=True means that you are trying to use an external TeX program.
Ok, so am I to understand that usetex=True is not supported for PDF/EPS
output? Can you explain what the Tex-like mathtext format parsed by
matplotlib is?
Thank you for your assistance,
--Jordan

Can you explain what the Tex-like mathtext format parsed by matplotlib is? matplotlib also has a built-in math formatting engine that does not use TeX itself. You can use it by leaving usetex=False (the default) and putting a '$' at the beginning and end of your TeX strings. Plotting.xlabel(r'$\alpha^2$') Unfortunately, the built-in engine only supports a subset of what TeX can do. That subset is much smaller in 0.90.1 than in the current SVN, where much progress has recently been made.

Re: [Matplotlib-users] Screen location
Dear John, First of all, thanks for your response. When I try this fig = figure() fig.canvas.manager.window.move(100,400) python tells me that window has no attribute move. It's strange because I can choose many differents attributes like fig.canvas.manager.window Tkinter.Tk instance at 0x019100F8 fig.canvas.manager.window.attributes bound method Tk.wm_attributes of Tkinter.Tk instance at 0x019100F8 fig.canvas.manager.window.frame bound method Tk.wm_frame of Tkinter.Tk instance at 0x019100F8 Then I've got a window class from Tk, but not the attriburte move. I need to install Tkinter apart? Pylab suports differents GUIs. When you install matplotlib/pylab package wich backends are installed? All? I know embedding it's a good option, but for the moment it's too much work for me. I've got not enought time. My programe has got differents modules that call pylab plots, and a simple GUI which call this modules. I hope I can move canvas frames. In the future I'll embedding matplotlib with some package like wxmpl, but in the future.

You will need to look at the API for the tk window to make the correct call. We do not provide an abstract API across the GUI windows we utilize internally. We give you access to the widget, and if you want to make GUI specific calls on it, good luck, but this is not encouraged or supported.

I think this is what you are looking for:
from pylab import figure, show
fig = figure()
ax = fig.add_subplot(111)
ax.axesFrame.set_data((0,0,1), (1,0,0))
ax.axesPatch.set_edgecolor('white')
ax.xaxis.set_ticks_position('bottom')
ax.yaxis.set_ticks_position('left')
ax.plot(range(10))
