Box and dot plots can be combined in order to achieve a brand new visualization. Still employing the car::Salaries data set framework, this recipe demonstrates how to bring them under the ggplot2 and plotly labels. Audience gets more detailed information when boxes and combined with dots.
Again, we need the car package locked and loaded:
> if( !require(car)){ install.packages('car')}Data frame Salaries will come from car package.
Now let's combine box and dot plots:
- Combine
geom_boxplot()andgeom_dotplot()to reach the desired effect:
> library(ggplot2) ; library(car)
> dot1 <- ggplot(Salaries, aes( x = rank, y = salary))
> dot1 + geom_boxplot(outlier.size = 0) +
geom_dotplot(binaxis = 'y',
dotsize = .3,
stackdir = 'center',
fill = 'red', alpha = .5)Following image (Figure 3.6) shows boxes displayed beneath the dots:
