8 Evaluation - Graphics area
The graphics area is shared by the analog and digital signals. The analog
signals always lie above the digital signals.
The most important control element within the graphics is the mouse. It is
used to perform different functions.
Left
mouse button Normally, the left mouse button will produce a zoom in the X-direction.
h Position the mouse pointer within the graphics.
h Press the left mouse button and hold it down.
h By dragging the mouse you can mark the time period
that has to be enlarged.
h Release the mouse button.
The graphics are automatically zoomed to the next possible time period.
Please note that more process data may be displayed than have been selec-
ted.
The function of the left mouse button can be controlled via the toolbar of the
software.
When using the Y-zoom, please note that the channels that have an auxiliary
Y-axis (or no Y-axis) are zoomed at a fixed ratio to the main Y-axis.
Consequently, the scaling range of the auxiliary Y-axes (or of the channels
without Y-axes) is expanded under certain conditions.
A fixed ratio to the main Y-axis is thus ensured. The diagram curves will appear
in the same relationship after the Y-zoom as before the zoom.
