[Matplotlib-users] clearing subplots

[Michel S. <sa...@sc...>]

Hello,

I finally got around to play with matplotlib and try to create node for 
using it within Vision (my visual programming environemnt).

I was wondering if there is a way the clear the area used by a given 
subplot.  cla() seesm the clear the data, but the axis and background 
remain.  The reason I am asking is that I envisioned that in my networks 
I would like to be able to create a Figure using one node and then have 
say a Histogram node be placed in a subplot and a scatter plot in 
another subplot (in the same figure).  Now if the Histogram node has a 
subplot parameter which can be modified by the user to move this 
particular graph to another location in the picture I need to get ride 
of what I drew in the previous location, but since parts of the figure 
might be generated by other nodes in the network I would not want to 
clear the whole figure.

Another question was whether it is possible to find out the figure 
number from the figure handle ?  If I pass the Figure instance between 
nodes to tell drawing node in which figure to place their graphical 
output I need a way to active the figure that comes as an input.  
Currently I add a number attribute to the figure when I create it in the 
figure node.

Thanks for any input .. and congratualtion on the very nice package !
