Thanks for your answer, the first row you mentioned is correct.
Thing is however that the y-axis on the first chart is from 6,5 to 9, and the second one from 0 to 10.
That makes the 2nd one more or less unreadable, where the first one is 'zoomed in' so the differences between the sets are better visible.
To bad if it's true that we cannot change it :(
