<pre><b>Usage: pl -gif errbar1.htm
or for postscript: pl -ps errbar1.htm | lp
In this example the means and standard deviations were already calculated,
so proc bars is used to render the bars. An alternative is to use proc
rangebar with meanmode option to calculate mean & standard deviation
and render bars.
Categories are used to position bars in X; proc catslide is used to
adjust the positioning slightly so that pairs of bars may be displayed
for each category.
