Hi everyone,
I use matplotlib to render a figure in a tkinter (the Tix library more
precisely) canvas.
It works very well but I can't turn off the autoscale (and I would like to),
even by setting
ax.set_autoscale_on(False). When I test with ax.get_autoscale_on(), the result
is False, but the
axes continues to autoscale.
I didn't had this problem in the past with ubuntu 8.04. I have it since I made
the update to the
8.10 distribution so I guess that it's because the version of matplotlib I use
have changed also
(but I don't remember the number of this previous version). Now I use python
2.5.2, Tix 8.4.0, mpl
0.98.3, numpy 1.2.1 ppa release, scipy 0.7.0 ppa release.
Here is the graphic part of my app :
class GraphFrame(Tix.Frame):
def __init__(self,master):
Tix.Frame.__init__(self,master,bd=10)
self.gen = Tix.Frame(self)
self.fps = Figure(figsize=(5,4),dpi=100,facecolor='w')
self.tlps = 'Phase Space'
self.xlps = {'xlabel' : r'$x$','fontsize' : 16}
self.ylps = {'ylabel' : r'$p$','rotation' : 'horizontal','fontsize' :
16}
self.aps = self.fps.add_subplot(111)
self.aps.set_title(self.tlps)
self.aps.set_xlabel(**self.xlps)
self.aps.set_ylabel(**self.ylps)
self.canvasps = FigureCanvasTkAgg(self.fps,master=self.gen)
self.canvasps.get_tk_widget().pack(side=Tix.TOP,fill=Tix.BOTH,expand=1)
self.toolbar = NavigationToolbar2TkAgg(self.canvasps, self.gen)
self.toolbar.update()
self.canvasps._tkcanvas.pack(side=Tix.TOP, fill=Tix.BOTH, expand=1)
self.gen.grid(row=0, columnspan=14, sticky='NWSE')
self.aps.set_autoscale_on(False) #doesn't work !!!
