GGU-GEO-GRAPH: "Manual resize (mouse)" menu item
You can alter the image coordinates graphically with the mouse. In the dialog box you are offered two choices.
You can use the coordinates of a section of the visualisation as the new image coordinates by marking the desired area with the mouse, pressing the left mouse button and holding the [Ctrl] and [Shift] keys. The scales of the x- and y-axes are adjusted accordingly. If the previous proportions (scale x-direction/scale y-direction) need to be retained, the "Proportional section" check box must be activated.
By activating the "Redefine origin" button you can change the image coordinates without altering the scale. In this way, you can quickly achieve the desired presentation with a suitably defined scale without annoying trial and error with the x/y coordinates.
