GGU-SLUGTEST: "Data range graphically" menu item
In principal, this is the same option as described in Section “"Data range via editor" menu item“, the difference being that you can comfortably define the data range graphically. All you have to do is simultaneously hold the [Shift] and [Ctrl] keys together with the left mouse button to define the required window.
If you activate the check box "Apply to time axis only" in the message box, only the new time coordinates are accepted; the y-axis with the height data remains unchanged (the diagram is stretched in x-direction).
