Statistics filters fail when only cell or row data exists.
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
When I run statistics filters (any, but descriptive will work as an example) on a dataset without point data (but with cell or row data), the variables listed in the array selection do not match the attribute mode combo box value. I've checked that the vtkSciVizStatisticsFilter is returning the correct information so it seems like the problem is somewhere in the ServerManager or Qt layers.
It's easy to reproduce... just use the Mandelbrot source, run it through PointToCellData (without passing point arrays), and then run Descriptive Statistics on the result.
