[Matplotlib-users] NavigationToolbar2Wx with mplot3d
Hi,
I have two questions about using NavigationToolbar2Wx with mplot3d.
1/ Initially the 3D scatter plot will rotate as usual with a mouse, but after
selecting the 'pan' or 'zoom' buttons the plot responds with some confusion.
How can I restore it to rotation only, i.e. disconnect the zoom or pan
behaviour?
2/ When using the 'save' button I get different behaviours depending on the
backend. With 'WXAgg' the saved png image shows only the axes, not the scatter
points. The scatter points and axes do appear correctly in a pdf file. Using
the 'WX' backend gives both scatter points and axes for the png file.
My full application has a mix of 2D and 3D plots (separate notebooks) and it
would be preferable for users if all plots could usedthe common toolbar.
I see this behaviour running matplotlib 1.0.1 with Python 2.6.6 and wxPython
2.8.11.0 under Windows XP with the example below.

# uncomment the following to use wx rather than wxagg
#matplotlib.use('WX')
#from matplotlib.backends.backend_wx import FigureCanvasWx as FigureCanvas
# comment out the following to use wx rather than wxagg

from matplotlib.backends.backend_wxagg import FigureCanvasWxAgg as FigureCanvas
from matplotlib.backends.backend_wx import NavigationToolbar2Wx

self.axes = Axes3D(self.figure)
xs = np.random.rand(100)
ys = np.random.rand(100)
zs = np.random.rand(100)
self.axes.scatter(xs, ys, zs)
self.sizer = wx.BoxSizer(wx.VERTICAL)

self.SetSizer(self.sizer)
self.Fit()
self.add_toolbar() # comment this out for no toolbar
def add_toolbar(self):
self.toolbar = NavigationToolbar2Wx(self.canvas)
self.toolbar.Realize()
if wx.Platform == '__WXMAC__':
# Mac platform (OSX 10.3, MacPython) does not seem to cope with
# having a toolbar in a sizer. This work-around gets the buttons
# back, but at the expense of having the toolbar at the top

else:

tw, th = self.toolbar.GetSizeTuple()
fw, fh = self.canvas.GetSizeTuple()
# By adding toolbar in sizer, we are able to put it at the bottom
# of the frame - so appearance is closer to GTK version.

self.toolbar.SetSize(wx.Size(fw, th))

However, if there is a difference between platforms with WxAgg backend, then it is likely a Wx bug and not a mpl bug (although the fact that the Wx backend worked is odd). We are putting out an RC of v1.1.0 later today. Could you try out that version within the next few days and let me know if it still happens for you?

Thanks! Josh This may be similar to a Qt-backend bug, which didn't take the toolbar into account when resizing the figure: https://github.com/matplotlib/matplotlib/pull/756 It doesn't quite fit, though, because Josh's original example shows a figure that's the correct size (but the axes doesn't fill the figure). The toolbar issue tended to squish the axes in the vertical direction (at least in the GUI window), whereas Josh's example is squished in the horizontal direction. Keith: Are you also using the Wx-backend? I don't have Wx installed so I can't provide much help. I've been planning to take a look at a similar issue in the Tk backend, but haven't had time.

Hi Josh,
I am not quite sure what information you need, but I have an application with
several wx notebooks, each with pages carrying related but different 2D and 3D
plots. I hope this overview covers what you want. In the code below I set up
the axes and toolbar in each panel ready to accept plots as required. I use
wxFormbuilder to create MyFrame1 and then this code to add graphs and other

display.

Re: [Matplotlib-users] wxpython matplotlib figure resize
Thanks Josh this is much appreciated. I will definitely have a look at this
approach.
Just for clarification, my code does only create the figures when the frame is
initialised. The plots are then updated/cleared as required.

Subject: Re: [Matplotlib-users] wxpython matplotlib figure resize
Yes, my apologies for being a bit vague. Hopefully the following can help you
out, but I can't make promises. It did fix the issue for me.
First off, from reading other threads about handling figures, it might be
better to use matplotlib.pylab.figure instead of matplotlib.figure. Apparently
the former registers the figure with a manager which allows for better cleanup.
Second, it looks to me from your code as if you are creating a figure every
time a new plot is created. Is this correct? Or are these functions just called
on startup? If you are creating a new figure each time for a plot, (which is
what I was originally doing) you should redesign so you keep the same figure
and then just update the subplots. Clear the figure and then add the
appropriate subplots. Here is a segment from my code:
def plot(figure, rows, cols, graph, title):
figure.clear()
plt.figure(figure.number)
pos_counter = 1
for g in graph:
g.axes = figure.add_subplot(rows, cols, pos_counter)
if title:
g.axes.set_title(g.plot_title)
plot_nx(g, plot_options=g.plot_options)
pos_counter = pos_counter + 1
figure.canvas.draw()
plt is the pylab module from matplotlib and plot_nx is an internal call to
networkx plotting capabiility (same as if you called the pyplot.plot). If you
do use pylab, make sure to include the plt.figure(figure.number) call as this
seems to be a bug (or perhaps this just is with networkx integration).
This setup works for me rather well. I no longer have to manually resize
anything.
I hope that helps. If not, I am at a loss for what would be a good way to
proceed. I, probably like you, spent a long time trying to figure this one out
and found this to be the best solution. It might be good to go with the clunky
mechanism since it works and wait until this is addressed later (if it is
indeed a bug)
Regards,
Josh
