You can get the axes through the Figure instance. (I don't know how you
have your embedding set up, but if it's something like
embedding_in_wx.py, there's the line "self.fig = Figure((9, 8), 75)", so
self.fig is a Figure instance).
self.fig.gca() # gets the current axes
self.fig.axes # is a Python list of axes -- useful if you have more
than one and you need to access a particular one of them
So, to do stuff with the grid:
self.fig.gca().grid(True)
To answer your other questions:
axes = self.fig.gca()
axes.set_xlabel("This is the x-axis label")
axes.set_ylabel("This is the y-axis label")
axes.set_xlim((-1.25, 1.25))
axes.set_ylim((-2.0, 2.0))
Cheers,
Mike
