Hi

I was wondering if it was possible, or if anyone has tried, to add a line to say an XY scatter graph to depict a threshold or some other level? For example in R you would use the

abline(h=3)

command to add a horizontal line to show a level at X=3. Is there an equivalent in the reporting collection, or do I have to construct the line on my datastream and plot it as a secondary data set?

Thanks for your help
