Plots of an exponential function a*exp(-b*X) for different values of a and b.
There are two subplots, a top one for a range of interest for X and a bottom one for positive values of X from zero to double the maximum X in the range of interest.
This example shows how a subplot can contain both a legend and an annotation.
