This will probably never happen but here are a few notes for the specification of a program that plots charts.
Stop Press: disovered ploticus: http://ploticus.sourceforge.net/doc/Welcome.html.
The inspiration is GnuPlot and my dissatisfaction with it.
What I need is a program that can create graphics for web pages. I need to be able to specify the size in pixels of the complete graphic and of the various elements (axis labels, legends, titles, markers, etc.).
What I don't need is a graphical display.
So here is a very rough draft of an object model. The +, *, ? signs have there usual regular expression meanings, numerals indicate specific counts, ranges have the obvious meaning.
Note that this is an *object* model not a class model. Items indented under another are referred to by the other. Note that this does not capture the interrelationships properly; for instance, the axes referred to by plotter are the same axes as those referred to by series.
