I am trying to draw a bar plot comparing multiple variables among two groups. var1 is the group indicator (1 or 2). The figure should have four bars. From left to right, the mean of var2 in group 1, the mean of var2 in group 2, the mean of var3 in group 1, and the mean of var3 in group 2. The first bar and second bar are side-by-side, so are the third and fourth bars. There is a gap between the second and the third bar. The first and third bars use one color (red), while the second and fourth bars use another color (blue).
Thank you in advance.
