pgplotter.plotxy2 - Function

	Package	display
	Module	plotter
	Tool	pgplotter

Plot X and Y vectors with auto-scaling using the right and upper axes.

Synopsis
plotxy2(x, y, xlab, ylab, tlab, plotlines, ptsymbol)

Arguments

x		An X vector
		Allowed:	float
y		A collection of Y vectors
		Allowed:	float
xlab		A label for the X axis
		Allowed:	string
ylab		A label for the Y axis
		Allowed:	string
tlab		A label for the plot title
		Allowed:	string
plotlines		Toggle for plotting lines or points
		Allowed:	Boolean
		Default:	T (lines)
ptsymbol		Symbol ID
		Allowed:	integer
		Default:	2

Returns
boolean

Description
This gplot1d-emulator plots a collection of Y vectors with auto-scaling against a single X vector using the right and upper axes. These axes will have separate labelling from the lower and left axes. If there is more than one Y vector, they should be arranged in a 2-D array with the first dimension being the number of vectors to plot and the second dimension being the length of each vector. The length of the X axis vector must be the same as the length of each Y vector. The color of each Y vector on the plot will be different for the first 16 plots, after that the colors will cycle through the same 16 colors. The order of these colors is the reverse order of that used in the ploty and plotxy1 functions.

Example

include 'pgplotter.g'
pg := pgplotter();
x := 1:100;
y1 := sin(x/10);
y2 := sqrt(x);
pg.plotxy1(x,y1,'X Index','Sine Function','Title');
pg.plotxy2(x,y2,,'SQRT Function');
pg.ptxt(105,5.5,270,0.5,'SQRT (X)');
