If the trigger requirement is met, then a vertical dotted line is displayed at the
interface between the values before and after the appearance of the trigger
requirement.
'Extras' 'Cursor Mode'
The easiest way to set a cursor in the monitoring area is to click there with the left
mouse button. A cursor appears and can be moved by the mouse. At the top of the
monitoring window the current x-position of the cursor is displayed. In the fields next
to 'Var 0', 'Var 1', ..., 'Var n' the value of the respective variable is shown.
Another way is the command 'Extras' 'Cursor mode'. With this command two vertical
lines will appear in the Sampling Trace. First they are laying one on the other. One of
the lines can be moved to the right or to the left by the arrow keys. By pressing
<Ctrl>+<left> or <Ctrl>+<right> the speed of the movement can be increased by factor
10.
If additionally the <Shift> key is pressed, the second line can be moved, showing the
difference to the first one.
'Extras' 'Multi Channel'
With this command you can alternate between single-channel and multi-channel
display of the Sampling Trace. In the event of a multi-channel display, there is a check
( ) in front of the menu item.
The multi-channel display has been preset. Here the display window is divided into as
many as eight display curves. For each curve the maximum and the minimum value
are displayed at the edge.
In a single-channel display, all curves are displayed with the same scaling factor and
are superimposed. This can be useful when displaying curve abnormalities.
'Extras' 'Show grid'
With this command you can switch on and off the grid in the graphic window. When
the grid is switched on, a check (9) will appear next to the menu item.
'Extras' 'Y Scaling'
With this command you can change the preset Y scaling of a curve in the trace display.
By doubleclicking on a curve you will also be given the dialog box 'Y-scaling'.
As long as option Automatic is activated, the default scaling will be used, which
depends on the type of the used variable. In case of enumeration variables the
enumeration values will be displayed at the scale. In order to change the scaling,
deactivate option 'Automatic' and enter the number of the respective curve (Channel)
and the new maximum (maximum y scale) and the new minimum value (minimum y
scale) on the y axis.
