Gnuplot Development
Revision as of 02:06, 25 August 2006 by Mojca Miklavec (talk | contribs) (just a few internal notes (the page should disappear as soon as possible ;))
Known bugs
- mathematics
\startGNUPLOTscript{exp} plot [0:3] 2/sqrt(pi)*exp(-x**2) t '$\frac{2}{\sqrt{\pi}}e^{-x^2}$' \stopGNUPLOTscript
- comments
\startGNUPLOTscript{sin} # this comment should be ignored plot sin(x) \stopGNUPLOTscript
- doesn't work with XeTeX yet
- Rotated PostScript images
-dAutoRotatePages=/PageByPage
TODO:
ConTeXt + terminal
- contour plot,
set style fill pattern
- images
- handling fonts / set label "font"
- colour palettes
- smooth shading
Efficiency
- optimize the number of gnuplot runs (if possible, gnuplot should be run only once)
- optimize the number of times for loading/converting an already used graphic
Gnuplot core
- CLIP lines & points
- MITTERED/BUTT
- encoding: bigger list, it's not updated in help (encoding), add utf-8
- pm3d - smooth shading
Obscure ideas
set decimalsign ','
based on language setting or locales
What has to be added to m-gnuplot.tex to support ConTeXt terminal
What has to be added to context.trm
High priority
- fix the syntax for
set terminal context
- write documentation
- [HTH] add \switchtobodyfont[whateverisprovided]\strut to evert \sometxt: try using (implementing first) \GPtext instead of \sometxt
Middle priority
- support different font sizes
- check if everything is documented well enough in help
Low priority
- implement with_image: once it's clear how to do it
- study the code for palettes, implement them and document them
- (need some interference with the core code) improve the code for
draw_color_smooth_box(MODE_SPLOT) in graph3d.c -> color.c
Legend
- [HTH] = Need Hans's or Taco's Help
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]
