Surely, e.g. you could use both y axes.

I understand that strings cannot be used in a bar graph, so I encode my newly created string variable. However, I lose the left alignment I previously enjoyed with the string variable and while the contents are the same the alignment is now right aligned (I have tried left aligning in the variable properties). Is this because what is being aligned is the numeric value behind the label?
