Different remarks about gnuplot development Hans's note:== Known bugs ==
Once we have lua in place it should not be that difficult to make a mechanism that works as follows:* context calls gnuplot and opens a socket* and starts waiting for gp to finish* when gnuplot needs dimensions it talks back via the socket* tex executes the command send by the socket* etcit needs some thinking but i thing that it is possible == What has to be fixed in m-gnuplot.tex == * Is it possible to get rid of "^M" at the end of lines* Addmathematics
{\executesystemcommandstartGNUPLOTscript{start /MIN pgnuplot sin}# this comment should be ignoredplot sin(x)\GNUPLOTfile.gpd}}stopGNUPLOTscript
* [HTH] change \startMPcode and \startMPpage to something like \strartGNUPLOTgraphic (once the support in m-gnuplot is written)
* [HTH] improve syntax for points, currently \sometxt{\GPpoint{NR}}
just a few internal notes (the page should disappear as soon as possible ;)

Different remarks about gnuplot development
== Notes ==
=== Hans's note ===
Once we have lua in place it should not be that difficult to make a mechanism that works as follows:
* context calls gnuplot and opens a socket
* and starts waiting for gp to finish
* when gnuplot needs dimensions it talks back via the socket
* tex executes the command send by the socket
* etc
it needs some thinking but i think that it is possible
=== closed curves in parametric plots ===
* it's probably not seen that easy, but if you want a circle with --cycle, set trange [0:2*pi]
