Dear Star Strider,
Thank you for your reply. Maybe I did not explain in in the best way. So let me try again.
Basically I want to plot the values in the first column on the y-axis and add the values of the second, third (and so on) column next to it. The values in first column represent the first experiment and the next columns are experiments done next in time. So I want to make 1 graph out of all sequential experiments.
Hope I explained it more clear now.
Kind Regards
