I am trying to find out if it is possible to set up a pivot grid with a local dataset that give the use more control over what to pivot. Basically I'd like to get a pivot grid to work more like an excel pivot table where I have a data set and then let the use configure what columns and rows they want out of that data. All examples seem to be using hardcoded column and row axes, is it possible to set up one or two defaults but then let the end user add more rows/columns via the configurator?
