Hi Bill,

I wanted to construct a Data object without having to load it into the
spreadsheet cell if possible. You said you can read it in from a file.
What class provides such a method? 

Tom, I was actually wondering if it was possible to extract the range
value for the "index" input field. ie. I'm trying to see if the input
"index" is mapped to the Visad parameter "iso-contour". I don't think I
can just access the value of the first spot in an array of the types
since index seems to occur in different places in the domain (and is
listed in a different order on the left column of the mapping dialog
box) for each csv file I've tried. Do you know if there is a way to see
what value "index" was mapped to?

Thanks,

You have to have a Data object before calling getType(). You can
either construct the Data object, or read it from a file.

Yes.

I think you'd get the same Exception with Flow, Text, Shape and
ShapeScale.

Good luck,
Bill
