vtkPExtractHistogram should produce empty output on non-root processess
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
To view the issue caused by this bug do the following:
- run ParaView in parallel
- apply histogram to any source
- look at histogram output in spreadsheet view
vtkPExtractHistogram produces valid output only on the root node, however it still produces non-empty recitlinear grids on other processes. The spreadsheet view simply delivers all the data from all the nodes to the client and hence we get invalid data on the client.
