[edit] Summary
An image of random numbers, with a hidden sine function, with a wavelength every 10 units. The bottom image shows the autocorrelation.
Made using R:
library(RSvgDevice)
x <- rnorm(100) + sin(2*pi*1:100/10)
devSVG("acf.pdf", width=3, height=4)
par(mfrow=c(2,1), mar=c(3.5, 3.5, 0.5, 0.5), mgp=c(2, 0.8, 0), cex=.7)
plot(x, type="o", col="blue", main=NA)
acf(x, 100, main=NA)
dev.off()
Minor edit for dashed line in bottom figure using Inkscape.
