I want to visualize a calculation based on two bar charts. For this I want to draw two bar charts side by side and a multiplication sign between both of them.
I wanted both axis environments and the multiplication sign to be nodes that I could position relative to each other using the positioning library but I noticed that the axis environments don't have a name that I could bind to.
This solution does the trick if everything is in one line. Positioning something below a chart would not be possible.
Is there a way to use relative positioning in my case?
