Communication. I'm sorry I wasn't clear. It is only the horizontal 
axis that I am having scaling & display problems with. If there are 2 
records, those two records would be spaced across the total width 
allocated to the table with each one being 1/2 of the chart object. 
if there are 10 records, they take up the same total width as the 
chart object is the same size but each record is 1/10 the width of 
the chart object. If I have no value for the 3rd thru 10th test, the 
charted line goes from the last score to 0 and then runs along the 
horizontal axis. The chart object charts a null value as a zero 
instead of not charting that test.

LOL

Which means that the legends print when they are not wanted nor 
needed (as the are already on the preprinted form.) The incorrect 
plots also print and are not covered up by the white rectangles that 
don't print.

Sorry for the mislead but the preprint comes from the image of the 
grid and the normal curves being on a pdf that has been pasted onto 
the form. Thus it is preprinted of sorts but the rectangles will in 
fact overlay the grids and curves so they won't print.
