Attached, find two macros files. The file, errorbars.tex implements plots with and without error bars. Each point in the plot is ``marked'', e.g. with a $\bullet$, or whatever. The second file, ``pointers.tex'', contains macros useful for pointing at things in a PiCTeX graph. E.g., if you've got data like: \put {\pointLeft{\Full}} [l] at 0.520833 42.4616 \plot 0 6. 0.0416667 6.36401 .... 0.520833 42.4616 / you'll get an arrow pointing left with the tip of the arrow at the endpoint of your data plot.
