Change the order of discrete axis.
Generate a factor with reversed levels or use a new ggplot2 option.
Examples.
df$X1 = with(df, factor(X1, levels = rev(levels(X1))))

flevels <- levels(PlantGrowth$group)
- Reverse the order of a discrete-valued axis
- Get the levels of the factor
flevels <- rev(flevels)
- "ctrl" "trt1" "trt2"
- Reverse the order
bp + scale_x_discrete(limits=flevels)
- "trt2" "trt1" "ctrl"
