In short:

I want to plot the mean of variable Y over variable X_1 to X_9. Each variable is a dummy variable. So, In total, I want to have 18 columns (of 02 colors for 0 and 1). How do I do that?

Background/Generalized Problem:

I had a checkbox question in a survey with 09 possible option. Participants could check any number of boxes. Each options were turned into dummy variable. Now I want graphically present the mean of a variable over this 09 dummy. If you know any article/tutorial on visualizing checkbox question, please share too.
