I cannot find any way to make the datasource language independent. If the filed is called Collumn1 (which would be the default name of a field in EN) well, in German that is... Which of course prevents the chart to be updated, even when reading the same datasource!
Renamed fields are not preserved when switching from a Display Language to another.
By default, Pivot Tables are not refreshed automatically, but you can specify that the Pivot Table is automatically refreshed when you open the workbook that contains the Pivot Table.
Note: If you experience display or formatting changes when you refresh the Pivot Table report, make sure that the Autofit column width on update and Preserve cell formatting on update check boxes are selected on the Layout & Format tab in the Pivot Table Options dialog box (Pivot Table Tools, Options tab, Pivot Table group, Options command).

The screenshots above demonstrate just a few of many possible pivot table layouts.
However, because the pivot table is itself constructed from the source data, the table itself might also change.
To illustrate how this works, let's change some source data, and then refresh the pivot table. Now let's change the City name from Minneapolis to St. When we refresh the pivot table, we see a new row for St.

When we refresh the pivot table, notice that the Minneapolis number shown in 2011 increases by ,000 , along with the subtotal for the Midwest, and the Grand Total for all regions. Paul, and the pivot table expands as needed to accommodate. Paul back to Minneapolis and refresh, the pivot table will be rebuilt without an entry for St. As you can see, refreshing a pivot table not only updates values, it also updates the structure of the table as needed to match the source data.
