Recipe Objective
How to plot bar chart in R? Bar charts provide visualization of categorical data into discrete groups. They represent a categorical type of data with rectangular bars either horizontally or vertically. A barplot () function is used for plotting a bar chart. The following recipe provides an example on a bar chart..
Step 1 - Create data for plotting
a <- c(5,10,15,20,15,10,5)
b <- c("A","B","C","D","E","F","G")
Step 2 -Apply barplot()
Syntax for bar plots - barplot(x,y,xlab,ylab,main) where, x - x axis input data y - y axis input data xlab - label to x axis ylab - lable to y axis main - title to the bar chart.
barplot(a, names.arg = b, xlab="Category", ylab="Values", col="orange", main="Values Vs Category")
