Node labels for plotting

[rittman]

Can we make the node labels for plotting the actual node names rather than an index? I don't want to update this before you do a merge with the master.

[mrittman]

Not sure what you mean by this. Can you give example and references to some lines of code?

[rittman]

It would be good to specify the node label when plotting, not merely the index since they may not be in the correct order.

Test script here showing the problem:

a = mbt.brainObj()

edges = [(0,2),
         (0,4),
         (0,6)]

locations = {0:(1,1,1),
             2:(2,2,2),
             4:(3,3,3),
             6:(4,4,4)}

a.G.add_edges_from(edges)
for n in a.G.nodes():
    a.G.node[n]['xyz'] = locations[n]

b = mbp.plotObj()

# this works:
b.plotBrainCoords(a)

# this works:
b.plotBrainCoords(a, nodes=[0,1,2,3])

# this does not work:
b.plotBrainCoords(a, nodes=[0,2,4,6])

Thanks fixed this for nodes. Do you need a similar function for edges?

[mrittman]

Merged with the master, will write some test code for plotting and add that soon.

[mrittman]

Test functions added to master.
