Hello,
Could someone please help me by posting the complete minimum code required to plot a value for a histogram? (The value I'm working with is your pip difference between Pair1 and Pair2 for instance)

I have been messing about with it by stealing bits from here and there, but from the bits I have copied from other indiors I can not work out how to specify a 0 point for the histogram bars to originate from, nor the amount of pubs back to be calculated. I would like to get a range /- .

Thanks very much.
John
