Create Cumulative Sum Chart with Count on Y-Axis in R using ggplot2
Cumulative sums are often used to display the running totals of values and these sums also help us to identify the overall total. In this way, we can analyze the variation in the running totals over time. To create the cumulative sum chart with count on Y-axis we can use stat_bin function of ggplot2 package.
Example
Consider the below data frame −
> x<-rnorm(50,1.5) > df<-data.frame(x) > head(df,20)
Output
x 1 1.755900133 2 1.185746239 3 0.821489888 4 1.358420721 5 2.719636441 6 2.885153151 7 1.131452570 8 0.302981998 9 0.433865254 10 2.373338327 11 0.428436149 12 1.835789725 13 2.600838211 14 2.108302471 15 1.164818373 16 1.547473189 17 2.870272096 18 1.790039472 19 -0.006816034 20 3.510828517
> tail(df,20)
Output
x 31 3.3137587 32 1.0945959 33 1.5224898 34 2.2356911 35 1.5971496 36 2.6768012 37 1.8453177 38 2.5820093 39 0.4334084 40 2.0123960 41 2.6038358 42 2.3482770 43 1.5645365 44 2.4985221 45 2.5645833 46 1.5095937 47 0.2791473 48 3.8218481 49 2.4270537 50 1.7294788
> sort(df$x)
Output

Loading ggplot2 package and creating cumulative sum chart with count on Y-axis −
> library(ggplot2) > ggplot(df,aes(x))+stat_bin(aes(y=cumsum(..count..)),geom="step",bins=30)
