Dan,
Thanks for this reply. What I really want to do is use the output of
getFilteredRows() as the chartWrapper input. I had a further question about
that. In particular, I wanted to see if it was possible to do Boolean
combinations of criteria across different columns. So if I have
getFilteredRows([{column: 3, value: 'category1'}, {column: 2, value:
'category2'}]
I interpret that in Boolean terms to mean rows where column 3 takes value
category1 AND column 2 takes value category2. However, what if I want to
select rows where column 3 takes value category1 OR column2 takes value
category2, or perhaps rows where column3 does NOT take value category1? Is
this possible within the syntax?
All feedback gratefully appreciated.
Nick
