SciDavis looks like a good match. My immediate task was to convert about a
dozen
sets of two-step vectors into summarizing graphs ... nearly sixty such plots
on
a recently finished webpage. Now that task is done (for the time being) and I
can
think about using SciDAVis for the same purpose. The first step is obvious,
but
adding the second step isn't. Off-list help would be much appreciated.
Another less pressing task (from a security standpoint) is to make graphical
surveyor's
plats, where a number of vectors of different angles and lengths are
daisy-chained
into a diagram of a piece of land ... for later comparison to aerial
photographs.
