In both cases you'll need to write a program with whatever you want to plot. If you want to plot Sin(x) you'd key in something like this:
ENDYep, even if you have just a single operation to be performed, you'll need a program.
Then, after having all of them loaded - DPLOT, PLOT and the program with whatever you want to plot - execute ([XEQ]) DPLOT (for display, LCD) or PLOT (for the 82240A or 82240B) and fill the parameter variables - YMIN, YMAX, AXIS, XMIN and XMAX - with their related contents. Then the program stops and shows current label (or blank display, IIRC) of the program to be plotted. This is the point you enter the label of the program you keyed in - FCN, in this case -. Press R/S and the function is plotted.
If you are using PLOT instead, you'll also have XINC amongst the parameter variables. This is used just to define how many points (step?) will be plotted between XMIN and XMAX.
Hope this helps a bit.
