Me­taPlot – Plot-ma­nip­u­la­tion macros for use in Me­ta­post

Me­taPlot is a set of Me­ta­post macros for ma­nip­u­lat­ing pre-gen­er­ated plots (and sim­i­lar ob­jects), and for­mat­ting them for in­clu­sion in a Me­ta­post fig­ure. The in­tent is that the plots can be gen­er­ated by some out­side pro­gram, in an ab­stract man­ner that does not re­quire mak­ing de­ci­sions about on-page siz­ing and lay­out, and then they can be im­ported into Me­taPlot and ar­ranged us­ing the full ca­pa­bil­i­ties of Me­ta­post. Me­ta­plot also in­cludes a very flex­i­ble set of macros for gen­er­at­ing plot axes, which may be use­ful in other con­texts as well.
Presently, Me­taPlot is in some­thing of a pre-re­lease beta state; it is quite func­tional, but the syn­tax of the com­mands is still po­ten­tially in flux.
