matplotlib-users Mailing List for matplotlib (Page 16)

I tried to build matplot lib (both 0.87 and 0.86.2) on Ubuntu Linux 5.10. =
The=20
first set of error messages convinced me to install the Tcl and Tk dev=20
packages.
The second run of errors is just really weird, and I'm not sure how to fix =
it.
Thanks,
Antoine

I need to control aspect ratio of the plot as visible on the screen or 
printed.. for example, a plotted circle or ellipse must come out with 
the right aspect ratio. (Note: printing is primary, we assume printer 
pixels are perfectly square, and we don't care if the screen pixels are 
not quite square.)
(Note to John -- I'm in Ted Drain's group at JPL, and I'm looking at 
this early.. I know you've been hired to create an ellipse primitive.)
So what would be a way of controlling aspect ratio? Can this be done via 
pylab, or better done through the OO interface? I know that I can resize 
the figure canvas, but to be strictly correct I need to know the length 
of the axes in pixels, not the figure canvas.

Hi,
I'm sorry, but removing the texcache doesn't help. I have patched the 
matplotlib code successfully to solve this problem. I'll submit the 
patch at the sf.net site.

Hi,
I have tried matplotlib 0.87 and bumped on a problem with the dpi 
settings. I have set "text.usetex=True" and I use the Agg backend. When 
I write a figure to a png file at different resolutions, the size of the 
text in pixels remains the same, while it should be the size relative to 
the image size that is invariant.
I'll send a patch in the near future, unless someone else is already 
working on this.

Toon

The call to semilogx calls ax.set_xscale which overrides your custom
formatter. The following should work
 ax.semilogx(x_axis, fp_y_axis, 'r', linewidth=0.1, markersize=2, label = "False Positive")
 formatter = FuncFormatter(log10Product)
 ax.xaxis.set_major_formatter(formatter)
Ie, set your formatter after any call to set_xscale or semilogx.

Hi everyone,
I have been using code similar to the below to format the labels on scatter plots with the x axis
set to a logarithmic scale. However when I try the below I still get the base and exponent instead
of the product (ie '10**2' instead of '100'). Can anyone tell me what I am doing wrong? Sorry
about the large data sample but I figured it was best to be as accurate as possible.
Thanks,
Derek

Dear all,
 
I would like to use Matplotlib with movpy (Movable Python - Movable Python
is a Windows distribution of Python that doesn't need to be installed. It
easily fits onto a USB memory stick.
http://www.voidspace.org.uk/python/movpy/)
With the great help of the Movable Python author, I manage to install pylab
on the stick as well. It even runs with iphyton! 
Unfortunately pylab writes all the fonts and stuff to the "home" dir of the
Windows PC. I tried to change the datapath in matplotlibrc, but I could not
manage to use a relative path. It crashed. A absolute path is no so good,
because USB Sticks can have different drive names on different Windows PCs.
Does somebody knows a solution to use a relative path for the datapath
directory?
Regards
Jens
 

I just compiled MPL (with NumPy for the numerix package) on my new 
intel-based MacBook. I used the png and freetype libraries installed 
via i-Installer (http://ii2.sf.net), which are available as universal 
(i.e., intel-compatible) binaries. AquaTk (universal) was already 
there.
I did install the latest 2.4 python from source, in order to get 
readline. After some testing with between the installed python2.3, 
and the new python2.4, it seems that the newer python is faster, and 
there are some glitches displaying graphics using the installed 
python2.3 that I have not yet worked out.
-Rob.

matplotlib will work with numpy, numarray *or* Numeric, but it doesn't
work with all three at the same time. You need to set your "numerix"
setting in your config file to agree with which package you are using
(and then restart python). An example rc file is at
http://matplotlib.sf.net/matplotlibrc
We provide a numerix compatibility layer which you can consider using
so you won't get into these troubles. This essentially guarantees
that the array object you are using is the same as the one you have
set in your configuration file
 import matplotlib.numerix as nx
 x=nx.array([1,2])
 hist(x)
You can inspect the value of the numerix parameter with
 import matplotlib
 print matplotlib.rcParams['numerix']
rcParams is a dictionary mapping a configuration parameter to a
value. Most of these can be changed dynamically at runtime, but two,
the 'numerix' and the 'backend' setting must be changed before
importing the numerix module and pylab, respectively, because these
trigger imports that are not easily undone. Most people just set
these once in their rc file and are done with it, but you can set them
in a script with 
 from matplotlib import rcParams
 rcParams['numerix] = 'numpy'
 rcParams['backend'] = 'PS'
 # it is now safe to import numerix and pylab
 import matplotlib.numerix as nx # you'll be using numpy
 import pylab # with the postscript backend as default

You had to change the function find_tcltk in setupext.py. There are a 
problem on suse with "tk.getvar('tcl_library')" who are pointing toward 
something like "/usr/share/lib/tcl" instead that where are really the 
library.

 try:
 tk=Tkinter.Tk() 
 except Tkinter.TclError:
 print "Using default library and include directories for Tcl and 
Tk because a"
 print "Tk window failed to open. You may need to define DISPLAY 
for Tk to work"
 print "so that setup can determine where your libraries are 
located."
 o.tcl_lib = "/usr/lib"
 o.tcl_inc = "/usr/include"

#change introduce to tell where are the library and the version
 o.tcl_lib = "/usr/lib"

I've finally figured out why I've been having trouble creating histograms=
.
 As it turns out, if you pass to hist() a datatype that is numpy.ndarray
instead of a Numeric array, you get the following error. Check this out:
>>> import numpy
>>> import Numeric
>>> from pylab import *
>>> y=3DNumeric.array([1,2])
>>> hist(y) # This works no problem
>>> x=3Dnumpy.array([1,2])
>>> hist(x)
Traceback (most recent call last):
 File "<stdin>", line 1, in ?
 File "/usr/lib/python2.4/site-packages/matplotlib/pylab.py", line 1857,
in hist
 ret =3D gca().hist(*args, **kwargs)
 File "/usr/lib/python2.4/site-packages/matplotlib/axes.py", line 1676,
in hist
 n,bins =3D matplotlib.mlab.hist(x, bins, normed)
 File "/usr/lib/python2.4/site-packages/matplotlib/mlab.py", line 621, i=
n
hist
 dy =3D (ymax-ymin)/bins
TypeError: unsupported operand type(s) for -: 'str' and 'str'
I'm not exactly sure why this is true, but I've empirically found this ou=
t
to be the case. If anyone knows why, I'd sure love to know.
Thanks,
Finny Kuruvilla

We have migrated the development repository from CVS to svn. You can
now get the latest source tree with 
 svn co https://svn.sourceforge.net/svnroot/matplotlib/trunk/matplotlib 
The CVS tree is now dead and should not be used.

Hi all,
Is matplotlib available via svn ?
 
Nils

Hi: I just added the oft-requested reversed colormaps to the trunk in 
svn. The reversed colormaps have '_r" appended to the name, so cm.jet 
reversed would be cm.jet_r.

=46rom the netpbm website:
"The PPM format is a lowest common denominator color image file format.
It should be noted that this format is egregiously inefficient. It is highl=
y =09
redundant, while containing a lot of information that the human eye can't=20
even discern. Furthermore, the format allows very little information about=
=20
the image besides basic color, which means you may have to couple a file in=
=20
this format with other independent information to get any decent use out of=
=20
it."
They go on:
"However, it is very easy to write and analyze programs to process this=20
format, and that is the point."
So just out of curiosity, what is this format used for?

Hi,
Afaik there is no support for ppm files within matplotlib.
Is it planned to add this format to the existing formats bmp, eps, jpg,
png, ps, svg ?
