I forgot to tell you thawt I have 2 Dimensions (class(Wert, 0.001) and LinieWert). The second dimension allows me to plot 4 Lines, because I have 4 columns with information (I used Crosstable in my skript).
I tried to add "Month" as dimension but if I put it in second position than, I cannot plot 8 lines (4 for August and 4 for Sept for example). I just plot 2 lines (Aug and Sept).
How can I solve this problem??
Thank you for your time!!!!!
