Pl attach a .twbx. We can't open .twb
Thanks Alan for the informative post.
However I have already done this to create my tableau chart.
The issue I am having is that I have two area charts in my primary axes and one line chart in the secondary axes ( as dual axes already, check my post please).
If I now want to add another line chart to my secondary axes, this is not supported.
I can add as many facts in my primary axes, but then I can not have mixed charts, like 2 as area and 1 as line all in one axes.
Hence I really do not know how to add this 4th line chart (lower part of my tableau dashboard) into my already dual axes chart (upper part of my tableau chart).
