[Matplotlib-users] Inset plot with a previously draw plot
Hi, I have a previously draw plot that I want to place as an inset in another figure. I've tried with passing the previously drawn axes as the `axes` parameter to the `add_axes` method of the figure, and also tried using the `set_axes` method of the new axes, without success: I get the new inset axes, but without the previously drawn plot, in both cases. The following code shows both approaches: # Passing the inset axes as a parameter to add_axes fig_in, ax_in = plt.subplots() ax_in.plot([1,2,3]) fig, ax = plt.subplots() ax.plot([1,2,1]) fig.add_axes([0.72, 0.72, 0.16, 0.16], axes=ax_in) # Using set_axes fig_in, ax_in = plt.subplots() ax_in.plot([1,2,3]) fig, ax = plt.subplots() ax.plot([1,2,1]) ax_new = fig.add_axes([0.72, 0.72, 0.16, 0.16]) ax_new.set_axes(ax_in) Any help with this will be appreciated.

[Matplotlib-users] Make markers in legend to appear only once
Hi: I am plotting using markers, in a similar way than this example: http://matplotlib.sourceforge.net/examples/pylab_examples/legend_demo2.html As you can see in the example above, the markers in the legend appear twice: " 'green circle' 'green circle' oscillatory". Is it possible to make the markers to appear only once, like " 'green circle' oscillatory" ?

[Matplotlib-users] RuntimeError('main thread is not in main loop', ) after terminating a multithread program
Hi:
I have a multithread program. One of the thread is using MPL to plot
some data. Everything works as expected, until the moment I terminate
the program. When the main thread terminate, I start getting this
message:
Exception exceptions.RuntimeError: RuntimeError('main thread is not in
main loop',) in > ignored
I get 8 of this message, and then the program finally stop.
I am stopping the thread before terminating. I also close the figure.
All the threads are running as Daemons
(thread_instance.setDaemon(True) ).
Any idea about what could be happening?
Regards,
Alejandro.

[Matplotlib-users] No zdata in motion_notify_event when using a 3D plot
Hi:
I am trying to use the event associated to motion_notify_event in a 3D
plot, and I found that the event does not have the zdata property.
The following code illustrate the problem:
##
from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
def on_hover(event):
print dir(event)
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
x = [1, 2, 3]
y = [1, 5, 4]
z = [3, 5, 6]
ax.scatter(x, y, z)
cid = fig.canvas.mpl_connect('motion_notify_event', on_hover)
plt.show()
##
When you move the mouse over the figure, you can see the properties of event:
['__doc__', '__init__', '__module__', '__str__',
'_update_enter_leave', 'button', 'canvas', 'dblclick', 'guiEvent',
'inaxes', 'key', 'lastevent', 'name', 'step', 'x', 'xdata', 'y',
'ydata']
There is xdata, ydata, but not zdata.
Is zdata missing or should I be using a different event type?
Alejandro.

[Matplotlib-users] I get a warning when running code with ipython, but not with python
Hi:
I just installed matplolib from source code, and Ipython using pip, in
Ubuntu 11.10.
When I run this code
### foo.py
import matplotlib.pyplot as plt
plt.plot([1,2,3,4])
plt.ylabel('some numbers')
plt.show()
##
in ipython, I get the following warning:
In [1]: %run foo.py
/usr/lib/python2.7/dist-packages/gtk-2.0/gtk/__init__.py:54: Warning:
ignoring sys.argv: it must be a list of strings
_gtk.init_check()
Other than the warning the plot looks OK.
Also, if I type each sentence in ipython, I don't get the warning. I
don't get a warning if I use the standard python interpreter either
(as in $ python foo.py).
Any clue about this? Should I report this in the Ipython mailing list?
I am running Ipython 0.11 and matplotlib 1.2.x.

[Matplotlib-users] Incorrect latex rendering for \hat{x} and \vec{x}
Hi:
I am getting incorrect renderings when using \hat{x} or \vec{x}. The
following code
#
import matplotlib.pylab as plt
plt.axes([0.1, 0.15, 0.8, 0.75])
plt.plot(range(10))
plt.xlabel(r'$\hat{y}$ $\vec{x}$ $x^2 + y^2$', fontsize=20)
plt.show()
#
produce the attached plot. Note that the "hat" and the "arrow" are in
the wrong place. The other Latex part looks OK.
I am running version 1.2.x (built from commit
11e528425e230a3e23d04202aea23d88d40d9c4c) and Ubuntu 11.10.
Any ideas about how to solve the problem?

[Matplotlib-users] Error when saving as PDF using $\alpha$ and 'text.usetex':True
Hi:
I am getting an error when I save a figure as PDF with a particular
configuration and when I use a greek latex leter (say $\alpha$) as a
ylabel. The following code illustrates the problem.
###
import matplotlib.pyplot as plt
import matplotlib as mpl
params = {
'text.usetex' : True,
'font.family': 'serif',
'font.serif' : ['Times'],
}
mpl.rcParams.update(params)
plt.figure()
plt.plot([1,2,3])
plt.ylabel(r'$\alpha$')
plt.savefig('f1.pdf')
###
When I run it I get
Traceback (most recent call last):

line 301, in transform
buffer.write(value)
TypeError: unicode argument expected, got 'str'
Note that with any of the following variations the code works as expected:
- If I use plt.ylabel(r'$x_2$') instead of plt.ylabel(r'$\alpha$).
- If I save as PNG instead of PDF.
- Use the default configuration (comment the mpl.rcParams.update(params) line).
I am using MPL verion 1.2.x (built from commit 396a6446).
Am I doing something wrong? Any idea how to solve it?
Alejandro.

[Matplotlib-users] Using legend with a stem plot
Hi:
I want to add a legend to a stem plot with two plots. The basic code is:
###
from pylab import *
x = [1,2,3,4,5]
y1 = [1, 2, 3, 4, 5]
y2 = [5, 4, 3, 2, 1]
subplot(211)
plot(x, y1, 'rx-')
plot(x, y2, 'bx-')
legend(('a', 'b'))
subplot(212)
stem(x, y1, 'r')
stem(x,y2, 'b')
legend(('a', 'b'))
show()
###
The left subplot is the same plot using plot instead of stem. You can
see the result here: http://imagebin.org/128376 .
I expect the legend for the stem case to look similar to the plot
case, however, for the stem, I get the two labels of the legend
associated with the first stem command: 'a' linked to the marker and
'b' linked to the stem line.
Is there any way to fix this? Is this a bug?
Alejandro.

[Matplotlib-users] Stair plot
Hi: Any suggestion for making a stair plot in Matplotlib (like the stairs function in Matlab)? The attached figure is the output of the following Matlab commands: x = 0:10; stairs(x); I guess it is a matter of using a zero-order hold interpolation rather than linear interpolation between the points in the plot command, but I haven't find how to do that.

[Matplotlib-users] Animating selected plot elements
Hi: I am trying to use this code http://tinyurl.com/44zcpfk (Scipy cookbook) to make an animation where the background is fix and only a line is updated. However, after executing the code, I only get a window with an empty plot. Some debugging shows that the update_line function is not being called. I changed the use of numerix by numpy with respect to the original code. Other than that is the same. Any advice on how to fix the problem? Or may be this way is obsolete, but all the animation examples I've found so far don't consider a fixed background. Alejandro. -- Xperia(TM) PLAY It's a major breakthrough.

Adding
import matplotlib
matplotlib.use('GTKAgg')
solved the problem.
But now I get this warning:
/usr/lib/pymodules/python2.6/matplotlib/backends/backend_gtk.py:621:
DeprecationWarning: Use the new widget gtk.Tooltip
self.tooltips = gtk.Tooltips()

that matter.

[Matplotlib-users] Can't render the \dagger LaTex symbol
