can I exchange the top x axis with the bottom one? OR can I append a scatter dot plot to a category plot?

First, thank you all persons for every help you did. Currently I am almost finishing my chart. and I begin to learn programming, beginning with 'make' and 'wavestats'.

As attached, what i did is making a scatter dot plot and then appending a category plot to it.

but the problem is category names at the x axis. for scatter dot plot, the name is bracketed by ' . So can I ask how to avoid the marker ' ? or can I move the x axis of category plot to the bottom?

Sincerely
