Question

How to show small digit the x axis,y axis value of histogram ggplot in r

Answer 1

this is my data frame:

year <- c("2010", "2011" , "2012", "2014")

contribution<-c(67885.7, 134488.9, 97661.8, 79957.9)

df<-data.frame(year, contribution)

and I'm trying to plot a histogram using ggplot2, but the thing is: I wanted the x-axis to be the years on "c", and the y-axis to be the amounts in "contribution" and I can't just do it on ggplot.

I wanted it to be like this: http://oi66.tinypic.com/106hqp0.jpg

I tried this Formatting histogram x-axis when working with dates using R but it just didn't work.. Would you have an advice for me?
