[plt-scheme] Is it possible to draw a vertical line using plot?

You can define your own plot types.  The science collection does histogram
(1D and 2D) plotting by extending the plot package.  They plot vertical
lines.  Here is a link to the histogram plotting extension from the science
collection.

Users of the science collection don't normally call this directly.  There
are histogram types that abstract it.
