Re: [Matplotlib-users] mpl_toolkits axes grid
Hi David and Ben and everybody reading along, Apparently I did not phrase my question too well. To clarify: I would like to have some 'subplots' with a width proportional to the amount of (equally spaced) data points. It seems to me that gridspec (http://matplotlib.org/users/gridspec.html) is just the tool I need - with this I only need to calculate the relative sizes of my subplots, but that's easy. Alas, I did not discover it until tonight. Thanks a lot for your help! Christian -- Everyone hates slow websites. So do we.

[Matplotlib-users] mpl_toolkits axes grid
Hi,It is quite some time ago since I was intensively using MPL. Perhaps I will not get the terminology right anymore. And now I hope to get some pointer for this particular problem:I would like to arange some line plots using a grid from left to right in a single plot / figure instance. Each of these plots is created from vectors (numpy arrays) of a different length. If I would place subplots of equal size to place these individual plots from left to right, all will appear with a different stretch/squeeze.My question now is: Is there a way to place different subplots of different sizes automatically? For all my plots I will encounter different number of individual line plots of different size.My approach so far (pseudocode):from mpl_toolkits.axes_grid1 import Gridimport pylab as pltfig = plt.figure(1, (5.5, 3.5))grid = Grid(fig, 111, # similar to subplot(111) nrows_ncols = (1, number_of_subplots), axes_pad = 0.1, add_all=True, label_mode = L, )for index in xrange(number_of_subplots): grid[index].???And now I just do not know how to get any further? How will I get the necessary extension for each subfigure/plot? Which is the most efficient way to accomplish all this? Should I import a different class, other than Grid?TIARegards,Christian -- Everyone hates slow websites. So do we.

[Matplotlib-users] state, plotting 3D? semilog axis possible?
Hi, I've lost touch with the state of mpl and starting to use it again. Apparently some of the gallery examples in 3D aren't working, but I think I found a workaround. However, is there a way to get 3D bar charts with semilog style (e.g. logarithmic x-axis?) Right now, I have: from mpl_toolkits.mplot3d import Axes3D import matplotlib.pyplot as plt import numpy as np snip prepare data /snip for size, val, timepoint in zip(tdata[::2], tdata[1::2], timepoints): cs = ['b'] * len(size) ax.bar(size, val, zs = timepoint, zdir = 'y', color=cs, alpha=0.8) as modified from one example I've found. Looks fine, except that the x-axis has to be logarithmic to make sense (data were sampled this way). TIA, Christian -- NEU: FreePhone - kostenlos mobil telefonieren und surfen!

Re: [Matplotlib-users] rotating markers
Thanks! Alas, this raises a NotImplementedError and although I'm still running version 0.99 of mpl, it seems like this is not yet implemented in the 'errorbar'-function to handle this - or am I mistaken?

It appears that different rotations are applied when the fillstyle is set to one of bottom, top, or left. full is another available fillstyle, which appears to take a unit rectangle and rotates that 45 degrees. Probably your best bet would be the 'top' fillstyle, which looks like it does a 90 degree rotation.

Re: [Matplotlib-users] Latex, Labels and PDF
Hoi Peter,
$\rm{some label text} (\mu V)$ becomes somelabeltext\muV
You could try
r$\rm{some\ label\ text} (\mu V)$
instead. (Note the backslashes and the 'raw' r in front of the string.)
This way the string should be interpreted fine. You can use the '\ ' to
force a space, but whether it's necessary depends on the string you want
to display, of course.
Possible statements in the head of your programs might be:
from matplotlib import rcParams
rcParams['text.fontname'] = 'cmr10'
rcParams['lines.markerfacecolor'] = None
from matplotlib import rc
rc('text', usetex=True)
rc('axes', hold=True)
(From a current program of mine. Of course, some statements have nothing
to do with your problem, but they might illustrate some options you
have.)
The wiki/Cookbook has some info (on pitfalls, too):
http://www.scipy.org/Cookbook/Matplotlib/UsingTex
http://www.scipy.org/Cookbook/Matplotlib/LaTeX_Examples
You probably know the mathtex module:
http://matplotlib.sourceforge.net/matplotlib.mathtext.html
the wheeler_demo:
http://matplotlib.sourceforge.net/screenshots/wheeler_demo.py
and the tex_demo:
http://matplotlib.sourceforge.net/screenshots/tex_demo.py
?
As for your eps2pdf-problem:
I don't know any straightforward solution (one that always gives a
pleasant output) for it, but had a similar problem lately. It seems that
MPLs eps-output is not well read in by many viewers / converters (that
statement correct?). Correcting the eps with eps2eps or trying to
convert the eps with some other software did not work well for me. My
solution was:
Producing plots in formats other then eps/ps (e. g. png), with
sufficient resolution and converting to the format the publisher wanted
with other software (e.g. gimp or see what's on our terminal
server ;-) ).
Currently I'm only using eps figures for import into LaTeX - works fine.

Re: [Matplotlib-users] eps file format
Thanks, John and Alan, That was fast! As for the fonts, yes, you can control this with rc. Sure, but what about the latex rendered parts? (I wonder whether it actually matters, but I'd like to be sure, because there so little time left ...)

[Matplotlib-users] line styles with hollow circles?
Hi, I'd like to plot experimental data points with fitted data through it. This time best would be to plot hollow circles for the experimental data. Pretty much like literal 'o's (except, of course, that passing 'o' results in thick circles). Is this possible somehow? TIA Christian - Take Surveys. Earn Cash.

Re: [Matplotlib-users] eps file format
As for the preview header, I suspect there arte 3rd part tools that can do this (ImageMagick?). We should be able to do it ourself with agg, but it would require someone to dig in and figure out the spec. JDH One last remark on this: Since so many journals demand this, would it be worth a feature request? (I don't have the time nor the skills to work on this.) One may think of this as one wishes (don't like these publishing companies and their demands, either), but matplotlib wants to enable its users to produce figures ready for publication, right?

[Matplotlib-users] list troubles
Hi, Sorry for posting to the list, but I had no clue who to address. Recently I had some troubles sending emails to the list, for they were bounced back with this delivery status notification: The following message to matplotlib-users@lists.sourceforge.net was undeliverable. The reason for the problem: 5.1.0 - Unknown address error 550-'Postmaster verification failed while checking [EMAIL PROTECTED]\n(result of earlier verification reused).\nSeveral RFCs state that you are required to have a postmaster\nmailbox for each mail domain. This host does not accept mail\nfrom domains whose servers reject the postmaster address.\nSender verify failed' What then follows is my entire mail I was going to send. Unsubscribing / Re-subscribing helped. matplotlib-users is the only list where I had such problems, but not the only one using Mailman I'm using. Could this be a problem with the mailserver I'm using? My apologies if this is not considered to be of general interest. Please reply directly to my address in this case.

As far as I know, mixing wxpython and pylab this way is BAD.
You should better choose between:
- (1)Launch pylab in a separate thread
- (2) (What I do) Using WxMPL and embedding a matplotlib plot in a
wxPanel or wxFrame. You have to use the OO interface to matplotlib.

Hi,
Agree with massimo. One brief example might help:
import matplotlib
matplotlib.use('WXAgg')
from pylab import gca
from matplotlib.backends.backend_wxagg import FigureCanvasWxAgg as
FigureCanvas
from matplotlib.font_manager import fontManager, FontProperties
from matplotlib.figure import Figure
from matplotlib.axes import Subplot
import matplotlib.numerix as numpy
from matplotlib.ticker import LogLocator, MultipleLocator
from matplotlib import rcParams
import wx
snip
class Your_Class(wx.Frame):
def __init__(self,parent,id,title):
wx.Frame.__init__(self,None,-1,Your_Title)
snip
self.fig = Figure(figsize=(7,5),dpi=100)
self.axes = self.fig.add_subplot(111)
self.canvas = FigureCanvas(self, -1, self.fig)
self.parent = self.canvas.GetParent()
self.canvas.mpl_connect('motion_notify_event',self.mouse_move)
snip: SomeSizer
SomeSizer.add(self.canvas, 1, wx.LEFT|wx.TOP|wx.GROW|wx.EXPAND)
#useful method examples:
def OnRefresh(self,event=None):
refreshes the plotting window
self.canvas.draw()
self.toolbar.update()
#then the actual drawing function:
def plot_data(self):
actual plotting function
raw_plot(self) #imported own function, see below
self.toolbar.update() #not necesarry, but might help
def raw_plot(parent):
# note that all meta data / parameters from the parent are accessible !
# e.g. color = parent.color
parent.fig.clear()
a = parent.fig.add_subplot(211)
etc. etc. etc.
Thought this might be helpful to get started. You might want to write things a
different way, though. Particularly the my application is a bit more than
just a short script, so feel free to drop anything you don't want.
One last thing: I'd recommend having a look at the matplotlib examples
('embedding_in_wx*.py').
Cheers,
Christian
