A histogram consists of parallel vertical bars that graphically shows the frequency distribution of a quantitative variable. The area of each bar is equal to the frequency of items found in each class.
Example
In the data set Marks, the histogram of the eruptions variable is a collection of parallel vertical bars showing the number of eruptions classified according to their durations.
Ex Syntax:
hist(input$grades,breaks=seq(from=0,to=11,by=1), main="Histogram of Grades",col.main="mediumblue",xlab="Grades",las=1,col=c("red","yellow","green","violet","orange","blue","pink","cyan","brown","bisque3"))
