Specifying a Zoom Factor for the Current Display
You can adapt the size of the current display to suit its contents by selecting the
menu command View > Zoom Factor.
If you select a zoom factor that would make text too small to be legible, the step
and transition names are no longer displayed and only the numbers of steps and
transitions are visible. You can, nevertheless, display step and transition names by
positioning the mouse pointer on the step or transition.
If you want to avoid this, you can specify minimum zoom factors for the various
views so that the display size never becomes illegible.
You can also revert to the previous zoom factor at any time.
Lasso Functions for Zooming
If you want to increase the size of a specific area, you can also use the lasso
function. Drag a rectangle round the area you want to zoom using the mouse.
Select the menu command View > Selected Area. Now only the selected area is
displayed in the S7-Graph work area.
Splitting the Work Area into Two Windows
With the menu command Window > Split, you can split the work area vertically
into two sections and display the sequencer at two different display levels at the
same time.
The left half of a split window is always displayed at the overview level. In the right
half of the split window, you can set any other display level.
Steps selected in the left-hand pane can be edited in the right-hand pane.
Navigating in the Split Window
With the menu command Window > Next Pane, you can switch backwards and
forwards between the two panes.
Buttons for Handling Windows
S7-Graph provides you with a button for toggling the message window on or off
and a button for changing between the split window and the simple window. This
allows you to set up the work area to suit your requirements.
