%
%	TeX macros to plot error bars with the PicTeX macros.
%
%	These macros are largely derived from the examples in the back
%	of the PiCTeX manual.
%
%	To plot with a mark at each data point, simply say
%
%	\plotWith mark M at x1 y1 x2 y2 .... xN yN /
%
%	where "M" is a mark character {e.g. $\bullet$}
%
%	To include error bars in the plot, say:
%
%	\plotWithErrorBars mark M at
%		x1 y1 e1
%		x2 y2 e2 .... xN yN eN
%	/
%
%	The line-breaking isn't needed. Marks are placed on the graph
%	at (xi, yi) for each data point. Vertical error bars are drawn
%	from (xi, yi + ei) to (xi, yi - ei).
%
%	The cross-bar at the top and bottom of the error bars is normally
%	5 pts, but can be changed by setting the \crossbarlength dimen.
