If you're asking how to do it interactively, just click on the zoom button
again, and you should be able to fire pick events by clicking again.

Hope that helps!

Hi all,

How can I use a pick event when I have used "Zoom to rectangle" before ?

Hello Ryan,

thanks for confirming the problem.  I've also seen that note, but I
thought "do not work" means that the methods raise an exception, not
that they arbitrarily ignore arguments :(

While the standard Axis class works for the cut-down example I posted,
it does not for what I'm trying to achieve (having a second x axis below
the main one).  I came up with that solution following the matplotlib
documentation:

http://matplotlib.org/mpl_toolkits/axes_grid/users/overview.html#axisartist-with-parasiteaxes

however I don't really understand why some of the contortions there are
necessary (they are not explained in the documentation).

Cheers,
Daniele

Daniele,

I noticed the same problem with the Qt backend. However, I was looking at
the documentation on the AxesGrid webpage here:
http://matplotlib.org/mpl_toolkits/axes_grid/users/overview.html
And I see the following warning:

axes_grid and axisartist (but not axes_grid1) uses a custom Axes class
(derived from the mpl’s original Axes class). As a side effect, some
commands (mostly tick-related) do not work. Use axes_grid1 to avoid this,
or see how things are different in axes_grid and axisartist (LINK needed)

Unfortunately, no link. But perhaps there is a way to avoid using the Axes
class from axisartist in your use case. For example, could you import the
Axes class as follows:

from matplotlib.axes import Axes

That seems to work with the Qt and PDF backends on Windows 7 (Anaconda
Python).

Ops, obvious mistake. It should read:

BUG = True
if BUG:
    ax1 = host_subplot(111 , axes_class=Axes)
else:
    ax1 = host_subplot(111)

Hello,

it investigated this a bit further and the problem presents itself only
when I use `mpl_toolkits.axisartist.Axes`. Here is a minimum example
that demonstrates the problem:

import numpy as np
import matplotlib.pyplot as plt

from mpl_toolkits.axes_grid1 import host_subplot
from mpl_toolkits.axisartist import Axes

x = np.linspace(0, 2*np.pi)
y = np.sin(x)

f = plt.figure()

BUG = True
if BUG:
    ax1 = host_subplot(111, axes_class=Axes)
else:
    ax1 = host_subplot(111, axes_class=Axes)

ax1.plot(x, y)
ax1.set_xlim(0, 2*np.pi)
ax1.set_xticks(np.linspace(0, 2*np.pi, 5))
ax1.set_xticklabels(['%.2f' % x for x in np.linspace(0, 2*np.pi, 5)],
fontsize=8)

plt.draw()
plt.show()

Cheers,
Daniele

Hi Daniele,

not sure, but it seems to work for me. Did you do a plt.draw() or
plt.show() to reflect the changes?

Kind regards,

Oliver

Hello,

I'm trying to change the font size for the tick labels. I've tried both
setting it explicitly when creating the labels:

  ax2.set_xticklabel(['%d' % x for x in arange(10)], fontsize=10)

or after:

  for label in ax2.get_xticklabels():
      label.set_fontsize(8)

but the rendering is unaffected by the setting.  This is with the MacOSX
backend and with the PDF backend.  Is it a bug or am I missing something?

Thanks. Best,
Daniele

Hi Matplotlib-users,

I found it was useful to be able to change the default 'Axis.labelpad'
parameter, since this value didn't scale when changing the default figure
size (in my opinion its easier to prepare figures for publication assuming
they'll need to fit in a 1-column figure). I don't consider myself
experienced enough to attempt to contribute a patch, but nevertheless here
is the hack I used in case anyone has a similar problem:

axis.py, line 652:
original: self.labelpad = 5
changed : self.labelpad = rcParams['axes.labelpad']

Then, in rcsetup.py, I added the line (at 578):
    'axes.labelpad' :        [5.0, validate_float],

This lets you put
axes.labelpad       : 3
for instance, in your matplotlibrc to change the default label padding.

Anyways, not sure if this is the right mailing list for this type of thing,
but just thought I'd contribute it nevertheless.

Best,
-- Peter

setupext.py.  CXX.check() contains

          return self._check_for_pkg_config('PyCXX', 'CXX/Extensions.hxx',
min_version='6.2.4')

which requires version 6.2.4 or later of CXX.  Nils has 6.2.3 and so this
check should fail and matplotlib should fall back to using the local copy
of CXX.  SetupPackage._check_for_pkg_config() does check min_version if CXX
is installed using pkg-config, but if it is not then min_version is ignored
as the function raises a CheckFailed error before min_version is
considered.  CXX.check() catches this error and uses the system-installed
CXX regardless of its version.

To check the CXX version we probably need to look in CXX/Version.hxx.  I am
not sure how to proceed; do you have any ideas Mike?

Nils, as a stopgap you could either remove your python-cxx and
python-cxx-devel rpms if you don't need them for anything else, or upgrade
them to 6.2.4.  There is a 6.2.4 on rpm.pbone.net even though there isn't
one on packman.links2linux.de.

I installed OS X Mavericks a few days ago and I am running Mapllotlib Version 1.3.1.
Everything works fine except that I get a warning every time i use the pyplot.show() command.

here is what it looks like:
----
Python[27325] <Error>: The function `CGContextErase' is obsolete and will be removed in an upcoming update. Unfortunately, this application, or a library it uses, is using this obsolete function, and is thereby contributing to an overall degradation of system performance.
---

I thought I should ask if this is serious and also if something can be done about it.

Best,
Bedartha

The problem persists in master.

What are those arrows for if not for cycling through figures? Is this
really the only way to accomplish what the OP wants here? By writing
an event handler?

That's my bad.  I've updated the PyPI entry.

I just realized that I replied to this off-list. Sending back out to the
entire list. (Sorry for the duplicate e-mail Christoph!)

No, your first assumption was correct. "figsize" refers to the size of the
whole figure.

What I meant to do in that example was abuse the fact that matplotlib will
happily add things beyond the figure boundaries. You can then abuse the
"bbox_inches" kwarg to savefig to show everything, while keeping the size
of the "data area" between the axes boundaries the same as the figsize.

My example there is actually completely wrong.  I meant to do this:

import numpy as np
import matplotlib.pyplot as plt

dpi = 80
data = np.random.random((100, 100))

height, width = np.array(data.shape, dtype=float) / dpi

fig = plt.figure(figsize=(width, height), dpi=dpi)
ax = fig.add_axes([0, 0, 1, 1])

ax.imshow(data, interpolation='none')
fig.savefig('test.png', bbox_inches='tight')

At any rate, I'm not quite sure if that's actually what you wanted, but
it's a useful trick in cases like this.

This has been requested before, and it probably wouldn't be that difficult
to implement. If you want to take a crack at it, try making orthographic
versions of the functions in mpl_toolkits/mplot3d/proj3d.py. The tricky
part will be getting the right projection hooked up, but for now, you could
just override the existing functions.

Cheers!

Thanks for your suggestion. I needed to do this, but it solved a different problem.

The compilation problem above appears to be caused by settings of CPPFLAGS and/or LDFLAGS that pointed to my macports installation. Unsetting these before compilation solved the compiler error.

However, the links you mentioned were also necessary. Without them matplotlib links against the system Tcl/TK in /System/Library, whereas Python's tkinter is linked to the one in /Library. This gives a clash at runtime:

"Class TKApplication is implemented in both /Library/Frameworks/Tk.framework/Versions/8.5/Tk and /System/Library/Frameworks/Tk.framework/Versions/8.5/Tk. One of the two will be used. Which one is undefined."

and a couple more of these. Thereafter it crashes. The links in /Developer/SDKs/MacOSX10.6.sdk/Library/Frameworks to the frameworks in /Library make the thing consistent.

I want to create a 3d plot with matplotlib. I've gotten it to work, and can
control the view (camera) angles, but I don't want any foreshortening /
perspective. Is there a way to just have a plain orthographic projection
instead?

Hello,
Congratulations for this new minor release !
Someone mentionned on python-list that it's not available on pypi. I
checked, and indeed it isn't.
Should we upload it there?
Thanks,
N

Hi, all,
It didn't work for me with mpl 1.3 but it does with 1.3.1 (openSuse 12.3,
python 2.7.3, 64-bit).

To install 1.3.1, I had to use the archive from SourceForge directly since
only 1.3.0 is listed on pypi (I used pip) -- could that be the source of
this issue for you?

Regards,
Paulo Meira

For what it is worth I see behaviour identical to Neal. I'm using a
development version of matplotlib (v1.4.x, sorry I don't know the hash of
the installed version) on 64-bit Linux (Ubuntu 12.04) and Python 2.7.3.
That probably doesn't help much, except to show that this is not specific
to just Neal!
