After you have drawn a working range, you can carry out a spline interpolation:

▪Open within the working range the context menu with the right mouse button.

▪Select the Interactive spline interpolation function.

As long as this mode is active, you can only add, edit (e.g. moving with the mouse) or delete points or repeat work steps, cancel them and zoom.

▪Add descriptor points or

▪edit the existing points (see ch. Shifting measured values vertically).

A cubic spline interpolation through the new points is automatically carried out after each step.

▪Adjust the plot to your requirements, for example by adding, deleting or editing points.

▪To complete the mode, activate the function from the working range context menu again
