hi all

sounds like a simple problem in feflow 5.3 but can't solve it:
in the halt and view results menue i want to plot concentration diagrams for a 1D segment in a 2D vertical model. everything fine so far. the only problem is, that for some cases the y-axis goes into the negative range, for others not. this in turn means that for optical representation they have a different vertical extension which simply expressed looks stupid if various diagrams are compared within the same figure. the only option to modify the diagrams seems to be the vertical exaggeration option. the help says it is only available if the diagram has been plotted once, but in my case it still does not work, i.e. i can't set a value into the corresponding field.

does anybody know how to deal with this problem?
thanks in advance!
