Re: [Bug-plotutils] legend feature for graph, etc.

[rsm]

Daniel and Ludovic, greetings.  I'm the plotutils maintainer,
and have been out of touch with e-mail for a couple of weeks.
I'm finally getting caught up.

I share your interest in getting things moving again, with
plotutils.  My own interest is primarily in libplot/libplotter,
and in low-level drawing primitives.  I always intended `graph'
to be a sample application based on libplot, and hoped that other
people would write additional ones.

Here are some comments on Daniel's suggestions in regard to
graph.

>Use as library (having graph functions in Plotutils).

This is a very good idea.  Ideally, there ought to be a
libgraph, which is built on top of libplot.  In turn,
libgraph could be linked into other applications, besides
graph.  Libgraph could gradually be extended to support
additional types of graph, such as polar graphs, 3-D graphs, etc.

Would you be interested in turning graph into a library?

This would be rather easy to add to graph (it would be
less ambitious than turning it into a library).

> Reading NaNs and Infs in data files.

This feature would be very easy to add to graph.

> Unicode support
> Transparency & pdf (I do eps -> pdf in the shell using a wrapper)

These would really be enhancements to libplot, on which graph
is based.  (Adding Unicode support to libplot would be a lot of work,
if it were implemented consistently across all output formats.)
Could you tell me more about your need for Unicode, and
especially about the issue of transparency and pdf's?
