Steve, Thank you, I think you are right in general (the multiply by 60000 is correct though). Since mucking about with my code a bit more it has disappeared. Just strange to see an additive, as opposed to multiplicative, error given the type of calcs that I am doing, hence my doubting the meaning of the label.
many thanks -Stuart Steve Schmerler said: >> lines1.extend(pylab.plot(In, inputFlow * 60000, 'g--')) > > Couldn't it be because of "inputFlow * 60000", which may cause the > plotted values to be large (so it is related to what you do > numerically)?
