Timesignals
To choose this diagram type highlight the radio button next to Timesignals, and
press Next. This leads to the next wizard step, the Signal Select dialog.
The "Signal Select" dialog (see Figure 5.8) defines for which channels and
input signals the results in one diagram will be visible. Modify the selection 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 included in the diagram. In Figure 5.8 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 colours in the
field to the right of the diagram panel will be displayed.
