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
functionality. The 'tickle' function is called when a notebook is selected for
display.
import wx
from matplotlib.backends.backend_wxagg import FigureCanvasWxAgg as FigureCanvas
from matplotlib.backends.backend_wxagg import NavigationToolbar2WxAgg
from matplotlib.figure import Figure
from mpl_toolkits.mplot3d import Axes3D
class ProjectFrame(bare_gui.MyFrame1):
def __init__( self, parent):
bare_gui.MyFrame1.__init__( self, parent)
...
self.Create2DGraph(self.CT_graph_1, "Current / %")#CT notebook
self.Create2DGraph(self.VT_graph_1, "Voltage/ %")#VT notebook
...
self.Show(True)
def Create2DGraph(self, panel, xlabel):
panel.figure = Figure(None)
panel.canvas = FigureCanvas(panel, -1, panel.figure)
panel.axes1 = panel.figure.add_subplot(2,1,1)
panel.axes2 = panel.figure.add_subplot(2,1,2)
panel.axes1.set_xlabel(xlabel)
panel.axes1.set_ylabel('Error / %')
panel.axes2.set_xlabel(xlabel)
panel.axes2.set_ylabel('Phase / crad')
panel.sizer = wx.BoxSizer(wx.VERTICAL)
panel.sizer.Add(panel.canvas, 1, wx.LEFT | wx.TOP | wx.GROW)
panel.SetSizer(panel.sizer)
panel.Fit()
self.add_2Dtoolbar(panel)
def add_2Dtoolbar(self, panel):
panel.toolbar = NavigationToolbar2WxAgg(panel.canvas)
panel.toolbar.Realize()
tw, th = panel.toolbar.GetSizeTuple()
fw, fh = panel.canvas.GetSizeTuple()
panel.toolbar.SetSize(wx.Size(fw, th))
panel.sizer.Add(panel.toolbar, 0, wx.LEFT | wx.EXPAND)
# update the axes menu on the toolbar
panel.toolbar.update()
def Create3DGraph(self, panel):
panel.figure = Figure(None)
panel.canvas = FigureCanvas(panel, -1, panel.figure)
panel.ax = Axes3D(panel.figure)
#these labels should be selected later for specific components
panel.ax.set_xlabel('Current / %')
panel.ax.set_ylabel('Phase / degree')
panel.ax.set_zlabel('Error / %')
panel.sizer = wx.BoxSizer(wx.VERTICAL)
panel.sizer.Add(panel.canvas, 1, wx.LEFT | wx.TOP | wx.GROW)
panel.SetSizer(panel.sizer)
panel.Fit()
self.add_2Dtoolbar(panel)

Hi Keith,
How are you storing the plot in the frame/panel?

Hi Josh,
Yes I too am using the wx backend.

Hi,
I am interested in a better solution to this problem, but I have used this
simple method to force the right size.
def tickle(self):
#gets frame to redraw and resize, not elegant.
if self.IsMaximized(): #then needs a kick
self.Restore()
self.Maximize()
else:
x,y = self.GetSize()
self.SetSize((x-1, y-1))
self.SetSize((x, y))
Regards,

Subject: [Matplotlib-users] wxpython matplotlib figure resize
Hi all,
I am currently trying to use matplotlib with wxPython and all is going well
except for one annoying issue that I can't figure out.
I initialize a wxcanvas object with a figure and then throughout the life of
the program I want the canvas' figure to change and display the corresponding
plot. I can get the change of figure, but when the program goes to plot, the
figure isn't the right size. It changes to the right size only when I manually
resize the figure (see attached images). Is there some command that I am
missing? This is the update sequence I am using:
self.figure = figure
self.canvas.figure.clear()
self.canvas.figure = self.figure
self.canvas.draw()
self.color_background()
#self.GetParent().Layout()
#self.SetSizer(self.main_sizer)
#self.Fit()
self.SendSizeEvent()
As you can tell from the comments (there are more in my code), I have tried a
variety of ways to update the figure off the bat.
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.
Best,
-Tony
