[Matplotlib-users] Re: Dynamic plots with matplotlib and wx on OS X

[Leighton P. <lp...@sc...>]

Hi,=0D=0A=0D=0AMany thanks (again) to Matt for his suggestions - I had a "D=

m.=0D=0A=0D=0AMatt's solution works on OS X, but I'm afraid I didn't specif=
y what my=0D=0Agoal was particularly well.  I'm aiming to dynamically updat=
e a=0D=0Amatplotlib plot embedded within a wx.Panel (or wx.Frame) from anot=
her=0D=0Aobject, whose internal state is changing so that the calling objec=
t's=0D=0Ainternal state is reflected in the matplotlib plot.  The wx.Timer=0D=
=0Asolution doesn't seem appropriate for that (though if I'm wrong, I'm=0D=0A=
happy to take advice).=0D=0A=0D=0AAfter some reading around, I worked up tw=
