[Matplotlib-users] MatplotlibDeprecationWarning
Hi, I get the following warning in some code I wrote for matplotlib-1.2. python2.7/site-packages/matplotlib-1.5.0-py2.7-linux-x86_64.egg/matplotlib/artist.py:221: MatplotlibDeprecationWarning: This has been deprecated in mpl 1.5, please use the axes property. A removal date has not been set. warnings.warn(_get_axes_msg, mplDeprecation, stacklevel=1) Clearly, I should use 'the axes property', but as a replacement for? The code base is relatively large, so it's not clear to me what triggers the warning.

Hi,
I spend some time writing up the question below on Stackoverflow
which immediately was closed as a duplicate of other posts. To my
best knowledge, these posts did not answer my questions - so I'll
try my luck here instead:
I am using the qt backengine for setting up a QWidget that embeds
a matplotlib scene. When the widget is closed it appears that many
of the matplotlib objects that were part of the plot still are
alive in Python space.
My question is basically the following: What actions should I take
to clean up the figure and axes objects etc. that were part of the
plot widget? The qt backend comes with a figure manager, but it
appears a little unclear how it should be used.
I have attached a small unit test example that sets up a plot.
When the plot appears, just close it, and the test will garbage
collects the plot, and then display info of the matplotlib objects
that are still alive in Python space. Clearly both the path of the
plot, and several Bbox objects are still referenced.
Our current unit test suite contains almost 1 GUI tests and
its imperative that proper object space clean up is done after
each test. Any help is much appreciated.
Best regards,
Mads
Would fig.clf() do what you need?
Ben Root
Thanks for the feedback.
The trick is to get this done automatically when the widget is closed.
If you look in backend_qt4.py in the constructor of FigureCanvasQT
you'll find
QtCore.QObject.connect(self, QtCore.SIGNAL('destroyed()'),
self.close_event)
which should perform the steps below when close_event is called
event = CloseEvent(s, self, guiEvent=guiEvent)
self.callbacks.process(s, event)
If I insert print statements, the signal is ignored with matplotlib
1.1.0, but called with 1.2.0 (which uses a lambda function in the above
connection).But inspecting pythons objects after the close() method is
called on the widget, it seems that - at least - the paths associated
with plot actually still exist.
So I'm just a bit worried if there already is existing functionality in
the FigureCanvasQTAgg object that can do these things for me. And if so,
how to use them?
Best regards,
Mads

[Matplotlib-users] Line2D visible in axes
Hi, I have an 'axes' and some Line2D instance 'line' which is part of the axes artists. Suppose the plot has been zoomed so only a small window of the original axes is visible. Is there a fast/convenient method that can be used to test if a Line2D object is visible at the current zoom level. Of course you can test with data = line.get_xydata() (x_0, x_1) = axes.get_xlim() (y_0, y_1) = axes.get_ylim() invisible_x = (data[:,0].max() x_0) or (data[:,0].min() x_1) invisible_y = (data[:,1].max() y_0) or (data[:,1].min() y_1) but there might be something more convenient method/approach for this.

Re: [Matplotlib-users] Label for axhline
Sterling,
Thanks - I ended up adding an extra y-tick with minor=True. Something
along these lines:
# Add Fermi line
y = self._bandstructure.fermiLevel()
self._axes.axhline(y=y, linestyle=':')
# Add Fermi tick
tick = self._axes.set_yticks([y], minor=True)[0]
tick.label1On = False
tick.label2On = True
self._axes.set_yticklabels([r'$\epsilon_\mathrm{F}$'], minor=True,
fontsize=font_size*1.19,
verticalalignment='center')
Evil?

I recommend trying a text object[1], with a transform which is a blended

[Matplotlib-users] Updating a colorbar
Hi, Suppose you do this: axes = self.figure().get_axes() contour = axes.contourf(x,y,z) colorbar = self.figure().colorbar(contour) Suppose that the contour data changes, can you update the colorbar with the new data?

For example, if I do
label = axes.yaxis.get_major_ticks()[2].label
label.set_fontsize(size)
label.set_rotation('vertical')
the font size and the orientation of the tick label is changed. However,
if try

the tick label is *not* modified.
Any clues?

I have attached a small example displaying a simple plot in a PyQt based

[Matplotlib-users] Build MPL with VS 2008 problem
Hi, I am trying to build MPL 1.1.0 with VS 2008 on Windows XP 32.

[Matplotlib-users] Aspect ratio of a circle
Hi, I am using the Qt4 based back engine for displaying a 2D plot in a widget. The plot typically contains lots of line plots. Suppose I add a CirclePolygon to the plot like this: circle = CirclePolygon((x,y), radius=0.04, edgecolor='black', facecolor='red', zorder=1) axes.add_patch(circle) Then when I start to zoom in the window the aspect ratio of the circle is not preserved (it appears like an ellipse). If you plot a line with points, displaying its points using circles, these circles do have their aspect ratio (and size) preserved. There must be some approach for achieving the same effect for a manually added circle.

Re: [Matplotlib-users] Aspect ratio of a circle
I tried that, but that will make the entire plot look very strange if xlim = [0;100] and ylim=[-1:1]. What I really want to do is add a scale free aspect ratio correct circle to the plot.

Re: [Matplotlib-users] Aspect ratio of a circle
Thanks. The intention is to make the added circle dragable by the mouse by listening to mouse press, move, and release. That means that I have to modify the data of the added scatter data. I believe that the axes.scatter() method returns a matplotlib.collections.CircleCollection object. How do I change the position of the circles (one circle) contained in this object?

The transform object assigned to the circles in plot() and scatter() are different than the default when you make a circle polygon yourself. The easiest way to get them is to just simply use scatter() and pass in your own size value. I hope that helps!
