Hello Duke, WoW !! Very amazing. I'm studying the code now. I copied
and pasted into my chart formula. Amazing. When I go to parameters and
play with the color choices as per your suggestion, and hit OK nothing
happens, No change in colors. My guess is that your original colors
are still coded into my chart formula. Do I also have to change them
in the chart formula before I change them in the parameters (Ctrl-R)?
Thanks Duke. Good work !!
