box
command,
you can tailor them a bit more with the axis
command.
cursor
invokes the device cursor (for devices that have one).
You can then read positions from the screen by positioning the cursor, then
typing any key except e
or q
. Those latter 2 keys are
used to exit the cursor routine.
end
or quit
causes SM to exit.
expand
changes the size of the points and characters drawn on the
screen, as well as the size of axis tickmarks.
format
allows you to specify the format of the numbers that are
plotted along the axes.
help
is a very important command. You can also specify
help on a particular command with help <command_name>
identification
plots an identification line at the top of the
graph, giving the date and some other information, of your choice.
label
allows you to plot a label on the graph, at the current
location. You can specify different fonts and symbols, as described in
the manual
(see section 'Label' in The SM Manual).
location
command. But in general, if you want to plot more than
one graph on the screen (or page) at once, you will probably use the
window
command (see section 'Window' in The SM Manual).
lweight
allows you to change the line thickness. This will also apply
to characters that are plotted.
notation
command allows you to specify the range of
numbers that you want written out in this way, as opposed to being
written out in exponential notation.
relocate
relocates the current plot position to wherever you
specify when you issue the relocate
command.
ticksize
is used to control the spacing of tickmarks on the axes.
Its most common use is to define a logarithmic axis. To do this, the
first and third argument to the ticksize command should be negative.
window
is used to draw more than one graph on a single screen
(or piece of paper). As the name implies, it divides the default plot window
into n by m subwindows. You can make the windows touch, if that is
what you want to do.
There are many more commands, which are described at the back of the manual. You will regret not reading about them.
