In the R code below, the fill colors of the dot plot are automatically controlled by the levels of dose : ggplot(ToothGrowth, aes(x=dose, y=len)) + geom_dotplot(binaxis='y', stackdir='center', fill="#FFAAD4") p<-ggplot(ToothGrowth, aes(x=dose, y=len, fill=dose)) + geom_dotplot(binaxis='y', stackdir='center') p Flexible stacked-dot plots of relatively small samples, and provisions for identifying points. This flexibility may be useful if you want to build a plot step by step (for example, for presentations or documents). character vector containing one or more variables to plot. The dot plot is responsive to resizing of the plot window: a vertical resizing does not affect the vertical spacing of the dots, and a horizontal resizing may lead to re-binning to fit well within the range.
