 Step changes/discontinuities can be displayed by using the same parameter setting for
two consecutive X values. A step change is only valid if it has a valid pair of variates.
Otherwise, extrapolation continues, starting at the last valid pair of variates.
[14-23] Example: Characteristic with step change
 If only one interpolation point, x1, in the negative range is defined, x2 exists with the
"0 %" Lenze setting being the valid interpolation point (x2 > x1), and a line is drawn
through both interpolation points:
