Lets say you want to plot in matplotlib from a csv file of historical stock data the 1st and 8th column on a graph.
I tried this and it didn't work:
figure()
plot(values[[:,0], [:,7]])
show()

Looks like your subscripting syntax is wrong. You probably want something more like:
t = range(len(values[:,0]))
plot(t, values[:,0], t, values[:,7])
