In Windows I recommend running iPython inside Console 
<http://sourceforge.net/projects/console/>
particularly for its vastly improved copy and pasting.

Third Google result for "copy paste in DOS prompt"
http://www.copy--paste.org/copy-paste-between-dos-windows.htm

Note that right-clicking is going to execute behavior, not bring up a contextual menu.

Right-click does nothing on the IPython window.

The Windows command console is, I think, a lost cause all together. I've 
tried a right-click on it with the same result as in IPython.
I'm using Win XP, and I hope they improve on Win 7, which I plan to 
install on all my machines this month.

Hi,

How do I get the coordinates of the ticks and their labels in a coordinate
system that I can feed to figtext or text?
I want to display some additional text near one of the ticklabels on the x
axis. Although I could get the coordinates for figtext using trial and
error, but is there a correct way of doing this (using transformations?) so
that my text does not move relative to the tick labels.

Thanks!
Abhi

I apologize for my previous posts.  I see that the PolyCollection object is
not supported by the legend command.  I will use a proxy artist as described
here <http://matplotlib.sourceforge.net/users/legend_guide.html>.
- Chuck

How might create a legend for an area chart made with PolyCollection objects
via the fill_between method?  For example, on the following chart,

import matplotlib.pyplot as plt
import numpy as np
fig = plt.figure()
ax = fig.add_subplot(111)
ind = np.arange(3)
y1 = np.array([1,2,3])
y2 = y1 * 2
a = ax.fill_between(ind, y1, np.zeros(len(ind)), facecolor='r', label='a')
b = ax.fill_between(ind, y2, y1, facecolor='b', label='b')
plt.show()

I would like to create a legend that displays the label for a and b and the
corresponding fill color.  Unlike with non-collections objects, when I call
ax.legend() I get an AttributeError and the following output,

AttributeError                            Traceback (most recent call last)

I updated the axes_grid toolkit in the svn, and I hope it is more useful.

Check the example

examples/axes_grid/demo_floating_axes.py

The output is attached.

Hi, I'm using IPython raw. I guess I'm not sure what a shell is in this
case. I used to work with Linux years ago and the shell concept was
clear there. I'm now simply a Win XP user. What advantages would be
available to use a shell?

In part of the thread above,(posted 57 minutes after the hour, I asked
how copy and paste operate? Quick IPyton seems to think it works quite
like a Win copy and paste. It doesn't work for me.

Below you've manage to post a session. How did that happen? Is there a
file that I can pick up that contains the log? From the ref manual, I
see this:
===============


      Manual capture of command output¶
 
<http://ipython.scipy.org/doc/manual/html/interactive/reference.html#manual-capture-of-command-output>

If the input line begins with two exclamation marks, !!, the command is
executed but its output is captured and returned as a python list, split
on newlines. Any output sent by the subprocess to standard error is
printed separately, so that the resulting list only captures standard
output. The !! syntax is a shorthand for the %sx magic command.

Finally, the %sc magic (short for ‘shell capture’) is similar to %sx,
but allowing more fine-grained control of the capture details, and ...
===============end

Maybe this is somehow you did it?

Do you have the LaTeX preview package installed and 
"pngmath_use_preview" set to True in your conf.py?

Copy and paste from a Windows command shell is different that copy and paste
from *nix command shell.

Right-click in the command window
Choose Mark from the drop-down menu
Select the (rectangular) region of text you want to copy.
Hit Return.

That does a copy operation.  Then go to your other application, and paste
however you like.

Well, that's interesting, but how did you copy and paste?
Quick Python offers this, but no explanation how to copy and paste.
The %hist command can show you all previous input, without line numbers 
if desired (option -n) so you can directly copy and paste code either 
back in IPython or in a text editor. You can also save all your history 
by turning on logging via %logstart; these logs can later be either 
reloaded as IPython sessions or used as code for your programs.
Aside from that, here's an example of what I'd like to copy. If it 
doesn't make it through, it's just a screen capture of part of the 
window's contents show the result of ls, cd, etc.

Image above this.

Hi
I discovered "forrmlayout" by Pierre Raybaut (http://code.google.com/p/formlayout/) and I would like to use it for plot configuration. Is it only for the PyQt backend? I'm using GtkAgg.

Mathew

All,

I tried using sphinx.ext.pngmath. See:  http://msemac.redwoods.edu/~darnold/html/cylinders.html

Note in Exercise 1 how z = 6 - 2x^2 is placed so its baseline does not  
align (it's lower) with the baseline of the text. How can I align the  
baselines?

David.

All,

Is there an "axis equal" command for mplot3d?

D.

I see a variance with replying to a post on this list and other Python 
lists. It appears to be a difference between the way people post. If I 
see From: ab...@xy... and To: mat...@li..., 
then Reply All gets both. If I see, From: jo...@xy... and To: my 
e-mail address (or any personal e-address), then Reply All only goes to 
the From e-address, which means I have to fill in the e-address for this 
mail list. Apparently, some people from outside using a mail program 
like Thunderbird. How do I get two for price of one, so to speak?

Comments?

Good. Thanks. Interesting that ls and pwd are used for Win, but that's 
fine. How do I copy parts of the window?  All I can do at the moment is 
sweep out a rectangular area with the mouse. It looks like I 
underestimated the need for  automagic.

(Old) folks,
   is there a greppable list of matplotlib functions and attributes
along the lines of PyQt4.api
     PyQt4.QtGui.QAbstractScrollArea.viewport() -> QWidget
     PyQt4.QtGui.QAbstractScrollArea.maximumViewportSize() -> QSize
     ...
Grep is really fast, really simple, and can | less
to grep again / highlight to home in.


Thanks, cheers

All,

Is there anything resembling Matlab's comet command?

D.

All,

Is there any way to rotate a 3D plot_wireframe?

This suggestion did not resolve the problem.

But here is the solution. I have no idea why the first version is not
working.
I changed the threading technique:
  - from gobject.idle_add(run) to the fig.canvas.mpl_connect('draw_event',
start_anim)

I think it can be only that... Any ideas?

import matplotlib
matplotlib.use('GTKAgg')
from pylab import figure, show
import gobject, gtk
import time

fig = figure()
ax = fig.add_subplot(111)
ax.set_xlim(0, 30)

#fig.subplots_adjust(left=0.3, bottom=0.3) # check for flipy bugs
ax.grid() # to ensure proper background restore

ax.get_xaxis().set_animated(True)

fig.canvas.draw()


def run():
	if run.background is None:
		run.background = fig.canvas.copy_from_bbox(fig.bbox)
	
	fig.canvas.restore_region(run.background)
	i = run.cnt
	ax.set_xlim(0+i,30+i)
	fig.draw_artist(ax.get_xaxis())
		
	fig.canvas.blit()
	
	if run.cnt == 180:
		gtk.main_quit()
		raise SystemExit
		
	run.cnt += 1
	time.sleep(0.1)	
	return True
			


def start_anim(event):
    gobject.idle_add(run)
    fig.canvas.mpl_disconnect(start_anim.cid)

start_anim.cid = fig.canvas.mpl_connect('draw_event', start_anim)


run.background = None
run.cnt = 0

show()

Thanks a lot. 
Effectively, that was the missing headers 
------
yum install libpng-devel.x86_64
yum install freetype-devel.x86_64
------


Thanks,

You do not have the freetype2 headers installed. On ubuntu, I think
they are provided by the libfreetype6-dev package.

The mathmpl uses matplotlib's built-in mathtext rendering engine to 
render the math, which does not currently support any of the "grid" 
environments from ams-latex, such as "align".  If you need those, look 
at sphinx.ext.pngmath.

Hello,

The Axes3D constructor accepts the keywords "azim" and "elev" to set  
the viewpoint of the figure.

As for the title, I could not find information in the examples or the  
api, so I suggest to add text with the text method. This solution  
lacks an automatic placement for the title, however.

I give an example in your code:

from mpl_toolkits.mplot3d import axes3d
import matplotlib.pyplot as plt
import numpy as np

fig=plt.figure()
ax=axes3d.Axes3D(fig,azim=120)
x=np.linspace(-2,2,40)
y=np.linspace(-2,2,40)

X, Y=np.meshgrid(x,y)
Z=6-2*X**2

ax.plot_wireframe(X,Y,Z)
ax.set_xlabel('x-axis')
ax.set_ylabel('y-axis')
ax.set_zlabel('z-axis')

ax.text(0,0,9,'My Title')

plt.show()
