I'm afraid I haven't been able to make very much progress with this on
my own. I tried calling get_children on the figure objects I have, and
then tried calling set_axes with the subplot of a new figure on each
of the children in the hope that this would bind them over, but after
playing a bit nothing I've tried seems to work.
Is it possible to do this, or even if it is is it perhaps too
complicated/involved to be worth while? (I had hoped it would be
relatively straightforward once I found the right combination of
get/set functions to move the plot objects over to the new subplot).
Thanks,
Robin

We need more information in order to help. What OS are you using, are you 
running the script from a command prompt or are you running it from the IDLE 
editor, are there any error messages that would help diagnose the problem, we 
need something to go on.

Thanks for your help
I use the code below , but the plot wont be diplayed on my screen .
matplotlib.use('TkAgg') 
import matplotlib.pylab as plt
fig = plt.figure() 
ax = fig.add_subplot(111) 
ax.plot(x, y, marker='o', linestyle='', markerfacecolor='green') 
ax.set_title('Some random dots') 
ax.set_xlabel('x') 
ax.set_ylabel('y') 
ax.grid(True) 
fig.savefig('myplot.png', dpi=100) 
plt.show() 
Would you please help me ?

If you don't want to save a figure, then you will need an interactive 
backend--not Agg, but TkAgg or GtkAgg etc. Then you end your script 
with "show()" (imported from pylab or matplotlib.pyplot), and the plot 
will be diplayed on your screen. (The plain Agg backend is useful only 
with "savefig(...)" to generate png files.)
Check out the "examples" directory in the distribution.

How should I darw and show a plot using Backend Agg , I don't want to save
figure , just show ?
