Someone just asked, "how do I map a 4th dimension to line color?" I was surprised to discover that the varcolor demo, which answers exactly this question, is nowhere to be found on http://gnuplot.sourceforge.net/demo_4.6/. How does one go about updating/creating a patch for the demo pages? |

If you want to contribute a new demo, go right ahead. Or are you asking how to get an existing demo like varcolor.dem included in the on-line collection? The thing is, there's not room on one page to index every demo in the collection. I thought that these two already covered the case in question http://gnuplot.sourceforge.net/demo_4.6/rgb_variable.html http://gnuplot.sourceforge.net/demo_cvs/heatmaps.html But it is correct that one uses points and the other surfaces, so perhaps it isn't obvious that the same commands would work for a plot "with lines".

Why not? I doubt many people run all the demos when they need help, and some distributions don't include the demos. The demos left out of the demos web page effectively don't exist for user help purposes. It might be worthwhile to explore a more image-centric layout. (http://gallery.r-enthusiasts.com/thumbs.php is disorganized, but gives a general idea.) People often know, visually, what they want, but not the correct names and keywords to get that result. |

(http://gallery.r-enthusiasts.com/thumbs.php) That gallery is pretty nice. If anyone wants to put together an equivalent interface for gnuplot demos, I'm all for it. But I think we would have to find a separate site to host that sort of dynamic content. So far as I know, SourceForge only offers to host static content. Then again, it is possible to do some pretty amazing stuff via CSS, so maybe... Ethan |

Even though their top-level description of project services only mentions static web content, if you drill down to https://sourceforge.net/apps/trac/sourceforge/wiki/Project%20web%20and%20developer%20web%20platform it seems to say that PHP scripting is supported. Not that I know anything about using PHP, but if someone wants to tackle it, I'll help set up the necessary SourceForge access. Any volunteers? Ethan |

Or do you have some auto-generation code to create those pages? Is there a version-controlled repository for the HTML/generator code? |

The scripts to generate the demos are in directory .../demo/html The top-level pages (index.html) on SourceForge have been manually tweaked a bit from the auto-generated ones, but basically doing make or make -f Makefile.svg of make -f Makefile.canvas will recreate a local copy of the on-line demos.
