There's something I'm just not getting today...
I've got a chart command that generates results from a series of searches, evals, and other processes. The net result is a nice little chart with results that looks like this:
Location 2019 2020 Delta
Main 980 1268 29.39 %
The 2019 and 2020 are indeed years. My issue is that Delta is calculated based on those 2 columns as
eval Delta=(('2020'-'2019')/'2019'*100)
This is fine for this year, but of course it means we'd have to edit this dashboard again next year.
How do I reference the relative column positions rather than the column names, or otherwise glean the column names from the dynamic data, in order to crunch the Delta value automagically?
