Uses: PLOT
|
||
This module contains two examples of how PLOT might be used to produce high level plotting facilities. The first example is a histogram primitive, and the second is a scatterplotter. The code is commented, and exploits most of the facilities in PLOT. The scatterplot example is the simpler of the two, and is suggested as a starting point.
|
||
(SCATPLOT y x pointlabels ylabel xlabel title symbol) [Function]
|
||
Generates of a scatterplot of y vs x which are numeric lists of equal length. If x in NIL, then y is plotted vs the integers from 1 to (LENGTH y). Pointlabels is a list of labels, one for each point plotted. Ylabel and xlabel are labels for the x and y axis respectively. Title is a title for the scatterplot. Symbol is the plotting symbol to use, must be a BITMAP; defaults to STAR.
|
||
Returns a PLOT.
|
||
(HISTPLOT batch label shade) [Function]
|
||
Batch is a list of numbers, or a list of pairs (number . frequency) whose histogram will be displayed. Label is an optional label for those numbers. Shade is a shade to use to fill the bars of the histogram (defaults to SHADE3). The case of all entries in batch being integers is treated specially.
