Firstly I agree that more examples would help make working out how to use the
various Grid (& Plot) options clearer. Setting a single option is certainly a
trap for beginners.
i.e. not:
('GRIDZOOM';0.5) grid data
But:
(,:'GRIDZOOM';0.5) grid data
But if you already know what a boxed 2-column name/value matrix looks like,
then it is pretty easy to know whether you have got it right or not by just
executing the left argument in the session and seeing if the result is a
2-column name/value matrix. If not, you can either experiment or ask on the
forum. There are many ways to do it though - here are three.
