Well kind Sir:
It did work especially after I saved the database. I swear, oops I
mean that I posit - that I tried that syntax also but didn't work
when I tried it the first time. Had other stuff (trendlines) on the
chart, hadn't saved the database, and had previously tried other
expressions so that may have affected the chart somehow. But at any
rate your solution worked, so many thanks.
Best regards to you -
respectfully yours,
aequalsz
