To choose this diagram type highlight the radio button next to Timesignals, and
press Next. This leads you to the next wizard step, the Signal Select dialog.
The "Signal Select" dialog (see Figure 6.35) allows selection of the channels
and input signals for which the results in one diagram shall be plotted. The
selection may be modified by clicking with the left mouse button on any of the
option buttons. This will add or remove the check mark in the button. A
checked button means the results for the selected signal will be drawn in the
diagram. In Figure 6.35 the results for the left channel of the reference and
the test signal were selected. Each signal will be drawn in a different colour. The
assignment of the colors can be seen in the field to the right of the diagram
panel.
