[and David provides an example code using xyouts]

just a short addendum: if you want to label the points with numerical
values, you should use the string function (which includes a format
option). Then you would build a label string array like

valstr = string(y,format="(f7.2)")

and put that out as David suggested

xyouts,x,y,valstr,align=0.5
