How to display all x labels in R barplot?

Question

This is a basic question but I am unable to find an answer. I am generating about 9 barplots within one panel and each barplot has about 12 bars. I am providing all the 12 l

Answer 1

R won't label every bar if the labels are too big.

I would suggest trying to rotate the labels vertically by passing in the las=2 argument to your plotting function.

If the labels are still too large, you can try shrinking the font by using the cex.names=.5 argument.

Sample Data for plot

sample_curve <- c(2.31,2.34,2.37,2.52,2.69,2.81,2.83,2.85,2.94, 3.03,  3.21,  3.33)   # create a sample curve
names(sample_curve)<-c("1 MO","2 MO","3 MO","6 MO","1 YR","2 YR","3 YR","5 YR","7 YR","10 YR","20 YR","30 YR") # label the curve

Example of plot with labels too big

barplot(sample_curve) # labels too big for the plot

Example of plot with labels rotated and small

barplot(sample_curve, las=2, cex.names=.5) # lables are rotated and smaller, so they fit
