Within your blend are you also joining on the CMD field? Is this join 'active' within this view? (i.e. it has the orange chain symbol next to the field in the dimensions list)
thank you a lot that was the mistake I think. The join did not work because in one sheet it was considered a string and in one other it was considered a number. I think it is correct now.
However now the graph looks correct (when I hover over the chart the numbers mentionned look correct), but the labels I added to clarify the graph are not. The numbers labeled are the same for all years and some are missing.
Any idea on what is happening?
Thank you a lot for your help.
