Thanks for the replay, the jsfile helped me achieve my goal. But I have noticed something wierd.
The graph’s columns seems to compare data from all the data in the graph not from the linked column that share the same data set.
The result of this is that the columns don’t have the actual size that you would exepct given the values that are attached to them from the CSV file.
I have attached a link to an picture bellow for better understanding: http://tinypic.com/r/9fvgnt/9
Hope you understand what my problem is, and you can help me again.
Thank you so much !
