Hi Kirk,
For some reason my reply didn't come back on my email
(tho it is on the website) so rather than waste bandwidth with a test message,
I'll waste it with a fast tweak to the code you asked about. This will
allow you to adjust the period for the comparison, as well as the color and
style of display. Enjoy.
per= Param("Change since X periods", 1,1,21,1);
Chg = C-Ref(C,-per);
Plot (Chg,
"Change over " +
WriteVal(per,2.0) + WriteIf(per==1," period", " periods"), ParamColor("Color"
,colorcycle), ParamStyle("Style",
styleLine, maskHistogram) ) ;
Peace and Justice ---

That worked perfectly, thank you! I guess I was just
trying to over-
think it.

all that results is a straight line. I tried it with the Plot
