Library:	plot

Quantlet:		plot
Description:		convenient function for plotting results. Creates a global variable (plotdisplay) that contains a plot with at most five dataparts.

Usage:	`plot (x1, {x2, x3, x4, x5})`
Input:
	`x1`	n x 2 matrix, containing x and y values for plot
	`x2 - x5`	n x 2 matrices, optional dataparts for the plot

Note:

plot creates the local object "plotdisplay" that overwrites existing ones. Use adddata(plotdisplay,1,1,<objects>) to plot new objects together with an already existing plot.

Example:

library("plot") x=1:10 y=x^2 plot(x~y)

Result:

plot is shown in the display plotdisplay

Example:

library("plot") x=1:10 y=x^2 plot(x,y)

Result:

An error window appears with the message: wrong argument type,
must be numeric in plot line: 52, show: wrong count of column.
An empty display will be open.
If you type plot(x,y) then you have two parameters
which are nx1 matrices. It has another meaning than plot(x~y),
where x~y is a nx2 matrix.

Example:

library("plot") x=1:10 y=x^2 plot(x~y) z=x~(1-x^2) adddata(plotdisplay, 1, 1, z)

Result:

plot of z together with the already plotted object
