For all quantites except angle and time, there may be gaps in the recorded values. For example when
spindle functional test is performed, torque values are not recorded. When the torque curve is displayed
on the graph, a small gap in the curve is shown when the spindle functional test was performed. Another
example is Gradient values which are only recorded when the restriction Gradient is active.

recorded. If many traces are displayed with different torque units, the torque unit for each trace can be
found in the identity list. This list is displayed by clicking on the button
