The Evaluation > Formula... command opens a dialog box for entering a mathematical formula for the active curve.
Formula
Enter a mathematical formula. Open a menu for entering the curve names by pressing the >> button.
New Name
Enter the name of the new curve. As a default, the name of the active curve is already in this field.
New Unit
Enter the unit for the new curve. As a default, the unit of the active curve is already in this field.
Insert New Curve
Select this checkbox if a new curve is to be inserted. In this case a copy of the active curve is created, to which the formula, name and unit need to be assigned. The active curve remains unchanged.
If you do not select this check box, the formula is applied to the active curve.
Use the Scaling > Optimize Graph command to optimally scale the new curve.
You can also change the name and unit of the new curve at any time later.
Name and entity
Please note that the original values of the curve are not stored. If the formula is used more than once, the formula will applied to the current, i.e. changed, value each time.
