HP 49g Graphing Calculator - Manual (Page 71)

Basic plotting
The HP 49G’s plotting application enables you to graph functions. You can
create the functions before opening the application, or create a function
once the plotting application is open.
You can also plot statistical data. Statistical data needs to be placed in a
matrix before it can be plotted. You can create the matrix before opening
the plotting application, or create it once the application is open.
You can plot any number of fimctions at one time; however, you can only
draw one statistical plot at a time. You can, however, superimpose a new
statistical plot over a previously drawn statistical plot.
