I’m new to Paraview, and I want to know how to get the average of the grid results for each row once I get the results.

The following procedure is one way to do this.
1. Manually select cells in each row.
2. Extract only selected cells with the **Extract Selection** Filter.
3. Calculate the average with **Python Calculator**.
`Expression`: `mean(DataName)`
