R : Basic Bar and Pie Chart

07 May

Bar Chart

Lets take the data frame example from basic line plot.

x=data.frame(wt = c(105, 120, 120, 160, 120, 145, 175, 160, 185, 210),ht = (61, 62, 63, 65, 65, 68, 69, 70, 72, 75)
# Partition R workspace in 1 * 2 matrix
barplot(x$ht, ylab="Height", width=8, space=.3,xlim=c(1,100), main="Height Plot - Vertical Bars")
barplot(x$ht, xlab="Height", width=8, space=.3,xlim=c(1,100), horiz=T, main="Height Plot - Horizontal Bars")



Group Bar Chart

Lets try to plot the group bar chart on 2013, 2014 rainfall from Jan-Dec (rainfall). beside=True play the trick here

y=as.matrix(sapply(z, as.numeric))
barplot(y, <strong>beside=T</strong>, main="Rainfall in 2013-14", col=c("blue","red"))


PIE Chart

Lets try to create pie chart with the rainfall data set (rainfall_2014). Try with simple pie chart.

pie(z$X2014, main="Rainfall in year 2014")


Lets try beautify the pie chart

pie(z$X2014, labels=z$Months, main="Rainfall in year 2014", radius=1.1, col=rainbow(length(z$Months)))
