To add space between bars within a group, make width smaller and set the value for position_dodge to be larger than width (Figure 3.14). The reason is simple – ggplot2 uses stacked bar charts by default, and there are two products in the stack for each quarter. There are two types of bar charts: geom_bar() and geom_col(). Data derived from ToothGrowth data sets are used. then come thes aesthetics, set in the aes() function: set the categoric variable for the X axis, use the numeric for the Y axis; finally call geom_bar(). These two are mandatory for any visualization. When you use position_dodge(width = 0.9), it spaces the bars so that the middle of each bar is right where it would be if the bar width were 0.9 and the bars were touching. Bar charts can be hard to look at. This article shows you how to make all sorts of bar charts with R and ggplot2. Let’s wrap things up next.
