Plotting 2 bars and 2 lines in a 2 y-axis graph

Hi Community!

I am trying to plot in a 2 y-axis graph 4 series of data (lets say a,b,c,d). The first 2 series (a,b) I want to have in bars according the primary y-axis and the other 2 (c,d) I want to have them as lines following the secondary y-axis.

I can do it, HOWEVER, the second line I plot (d) is shown as an accumalated value together with c (c+d). Why does that happen? Can anybody help me on plotting the second line (d) with original values?!

Thanks a lot community! :-)

Best

Oh yeah.... a mistake, sorry for that!
