Apply to X-Y Table

This option applies the current calculation to the full X-Y data table. The X-calculation, if present, is first applied to the full data table, then the Y-calculation, if present, is applied to the full table. Finally, the weight calculation is applied, if present, again to the full table. If you have an X calculation that references Y, and a Y calculation that references X, note that the X calculation will use the original Y and the Y calculation will use the modified X.

Undo

After the calculation is applied, you are presented with a TableCurve 2D Graph that graphically renders the data after the calculation has been applied. You can undo the calculation if you are not satisfied with the results or if you want to experiment with different calculations. If you choose Undo, the original data will be restored. Choose OK to accept the modifications.

If Background Thread Fitting is active, the fitting will be initiated as soon as the calculation is applied. The fitting will thus be taking place in the background when you are inspecting the result of the calculation in the TableCurve 2D Graph.
