Ok - I think the documentation is confusing. At least, I'm confused.
The notation to use with the ChartWrapper is:
array_of_columns_desired = [...]
wrapper.setView({columns:array_of_columns_desired}]
Passing ChartWrapper.setView() a DataView object, even *without* the
toJSON, doesn't seem to work. That's what I was trying to do, example
here: http://jsfiddle.net/rYRD4/4/
I had mistakenly assumed you could pass a DataView object to setView.
But that appears to be incorrect. I'll use the notation you had going
forward.
thanks,
