I have prepared a bar graph with the following data and code. There are two yvars with different scales so I am using axis(1) and axis(2) and overlaying two graphs. The bars of the overlaid graphs overlap. Now I wish to separate the maroon and white bars so they do not overlap.
Any suggestions would be highly welcome.
