- Variable:
**graph:dimensions** -
A list of the width and height of the graph to be plotted using

`plot`

.

- Function:
**plot***func x1 x2 npts* - Function:
**plot***func x1 x2* Creates and displays using

`(system "gv tmp.eps")`

an encapsulated PostScript graph of the function of one argument`func`over the range`x1`to`x2`. If the optional integer argument`npts`is supplied, it specifies the number of points to evaluate`func`at.

- Function:
**plot***x1 x2 npts func1 func2 …* Creates and displays an encapsulated PostScript graph of the one-argument functions

`func1`,`func2`, ... over the range`x1`to`x2`at`npts`points.

- Function:
**plot***coords x-label y-label* `coords`is a list or vector of coordinates, lists of x and y coordinates.`x-label`and`y-label`are strings with which to label the x and y axes.
