The below sample graph was created using R, for an example I came across while reading (on Distribution of time until customer x arrives):
t <- seq(0,1,0.01)
ft <- 100*t*exp(-10*t)
plot(t,ft,type="l", xlab="T", ylab="f(t)")
title(main=expression(paste("Probability density function of ", Gamma(2,frac(1,10)))));
The graph looks like a Percent Point Function, even though it isn't exactly.Am trying to understand on how I interpret it, but am not getting it.
Can someone help on how to read the above plot?
Thanks,

maintitle asserts, this is a probability density function. As you might imagine, this basic tool appears in thousands of posts here, many of which will illuminate the question by showing how such plots are to be understood and read. The basics are explained in the apparent duplicate. – whuber Aug 20 '14 at 13:45
