SuperMongo is a plotting program that is excellent for plotting in 2D (just don't fall in love with it like some professors)

To start supermongo cd into your working directory and type sm at the prompt

cl>sm

: This is what the sm command prompt looks like

You can enter commands one at a time in the command line but the best way to work is to write a SM script and run it.
Write a script and save it as "file.sm"
Run scritp with:

: input file.sm

#You need a space before your commands (yes Mike, I know its retarded)

  device x11 -bg white	#sets the device to output to
#  device postfile sample.ps
  erase 			#erases any data in the device
  define TeX_strings 1	#turns on Latex fonts
  expand 1.0001		#changes font size
  ctype black			#changes color to black

type "ls" at the command prompt to get a list of all the commands available
type "help command" to get information on any command
useful commands to look up:
ticksize       	makes log ticks
get_hist      	bins up your data for you
box              	controls axis labels
lines            	controls what lines to read from file
add_ctype   	you can define your own color
ltype            	line type
ptype          	point type
chdir		change directory



Macros can help to unclutter your script.
