Separate place for selected y parameters

[GoogleCodeExporter]

Jannis:
The selected y-axis parameters we should display them additionally together 
as a list with the checkboxes also. If we deselect one y-axis parameter from 
the y-parameter list then this parameter should be removed from the 
additional list where only the selected y-axis parameters are displayed. Now 
it is not so user friendly because to delete a parameter I have to search it 
in the y-axis column.
