Barplot

A bar chart or bar plot displays rectangular bars with lengths proportional to the values that they represent. The bars can be plotted vertically or horizontally. One axis of the chart shows

the specific categories being compared, and the other axis represents a discrete value. In R, they are made using the barplot function. Bars can be grouped by categories,

making grouped barplot. Barplot must not be confused with histogram nor with boxplot.
