[Matplotlib-users] graphical graph - how to

[Josè L. M. <jos...@ya...>]

Hi experts!

I have: 

* a list of Q 'NODES'=[(x,y)_1,........, (x,y)_Q], where each element 
(x,y) represent the spatial position of the node in 2D Cartesian space.
* a matrix 'H' with QxQ elements {H_k,l}. 
H_k,l=0 if nodes 'k' and 'l' aren't joined by a edge, and H_k,l = the length of the edge that connects these nodes.
* a matrix 'Z' with QxQ elements {Z_k,l}. 
Z_k,l=0 if nodes 'k' and 'l' aren't joined by a edge, and Z_k,l = intensity_k,l (a intensity scale of the edge, 0<intensity<I-max) if these nodes are connected.

I want to draw the nodes in their spatial position, connected by the edges, and use a color scale for the 'intensity'.

How must I do that?

Waiting for your answers.

Thanks a lot!

Best regards,
José Luis
