Hi Matthias, You've got 2 solutions. One on the front panel, one dynamically. On the front panel, right click on your intensity graph -> Properties -> Scales -> no auto scale for X, no-auto scale for Y and your intensity graphs won't scale automatically anymore. On the diagram, create a property node of your intensity graph and put a 0 for the properties ScaleX -> Auto adjust and ScaleY -> Auto-adjust. These two operations have the same effect on the auto scaling of the graph. Try and do the same operation for Z axis and see what happens.
Hope this helps ! Julien
