No patches I'm afraid. But feedback goes here:
1) The label text of the following key element takes the color of the
preceding key symbol. Minimal example:
set terminal lua tikz fulldoc size 15cm,7cm context
set output 'plot.tex'
set xrange [ 0 : 13 ]
f1(x)=sqrt(x)
f2(x)=sqrt(x*0.8)-3
plot f1(x) lc rgb 'blue', f2(x)
Confirmed. I had the problems with that in my terminal as well, but I
think that it was a buglet in metapost back then; oh, good old
memories ... :) :) :) I didn't check the details about this one.
2) Negative axis labels are set with hyphen instead of proper minus sign,
which should be longer (see example above).
I'm not sure if this should really be fixed automatically or not. In
order to fix this one would have to patch gnuplot core.
I forgot the details how to do it (I can find it out), but you can
configure the layout of labels. In particular you may enclose the
number into math delimiters ($). Maybe something like
set format y $%.1f$
would work (you might want to change the size of left margin then).
Doing any other kind of magic would be a bit dangerous. Keep in mind
that
plot 'x.dat' u 1:(2*$2)
will also fail since TeX will interpret $ as math delimiter. But
changing that behaviour would have other undesirable effects.
3) First I thought luatex hangs but then I noticed TikZ is awfully slow when
drawing plots with large amounts of data points (the tikzpicture had about
3000 lines). I can speed this up by reducing the size by invoking plot with:

I wonder if there is a smarter way to do this in gnuplot.
Using bitmap terminals. A while back I was dreaming about having
mixed-mode with one terminal creating text labels and the other one
(png for example) drawing the plot. But this needs some extra
programming effort.
You would stumble against the same problem when using PS or PDF
terminal, maybe only at a slightly bigger number of points.
What I did for my theory of chaos reports and the million-of-points
plots in my thesis was to create an empty plot with ConTeXt terminal,
create a borderless plot with PNG and then manually insert PNG into
the generated ConTeXt output, which you could do with TikZ output as
well. It requires more effort, but there is no other way to speed up
vector graphics. They are simply not suitable for drawing millions of
points on the same plot.
(Gnuplot also has a keyword 'every' to reduce the number of points,
but in my case I wanted to plot all of them.)

Hej Mojca, thank you for your answer! Well, that was surprisingly easy - I
should have checked the manual first (I was just about to write an ugly hack

set format $%g$
gives the default label format (only enclosed in $) for all axes.

I'd probably do the same in that case. But unlike you I have a lot less points
- 5000 points instead of millions. Loot at this example, which is the slightly
modified random demo script taken from the gnuplot page:
set terminal context size 15.0cm,10.5cm standalone
set output 'randomCtx.tex'
set dummy t,y
unset key
set parametric
set samples 5000, 5000
set style function dots
set title Lattice test for random numbers
set xlabel rand(n) -
set xrange [ 0.0 : 1.0 ] noreverse nowriteback
set ylabel rand(n + 1) -
set yrange [ 0.0 : 1.0 ] noreverse nowriteback
set zlabel rand(n + 2) -
set zrange [ 0.0 : 1.0 ] noreverse nowriteback
plot rand(0), rand(0)
set terminal lua tikz context size 15.0cm,10.5cm fulldoc
set output 'randomLua.tex'
replot
Now look at the timing of processing the output files with context (final run
only):
context randomCtx.tex - 3.150 seconds.
context randomLua.tex - 23.658 seconds.
Further increasing the number of points to 15000 results in 8.978 vs. 62.878
seconds. Quite a big difference in processing time!
(Gnuplot also has a keyword 'every' to reduce the number of points,
but in my case I wanted to plot all of them.)
True, but suppose you don't have evenly spaced data points. Then you don't want
every other line but one point every 5 kilometres or something the like.
Especially for line drawings it would be beneficial not to place every single
point. Instead consecutive points should be skipped if they are close to each
other (with regard to plot units) - it makes no sense to include points which
you won't see anyway. This could be done by defining a grid with a certain
(user defined) resolution and rounding the coordinates (plot units) of a line
point to the nearest grid node. All consecutive line points falling on the same
grid node should not be passed on to terminal drivers. The psxy utility of GMT
(http://gmt.soest.hawaii.edu/) does this for instance. I am not aware of such a
functionality within gnuplot but it would be a nice feature.
Best wishes,
Florian

I am not aware of such a functionality within gnuplot but it would be a nice feature. But this is an issue of Gnuplot, not something that a terminal writer is supposed to think of. One thing that I did implement in ConTeXt was that if I get instructions move_to(10,3) line_to(11,8) line_to(11,8) line_to(11,9) then one line_to(11,8) will be ignored (resolution is hard-coded in the terminal, but you could draw a smaller plot and then magnify it which would seemingly decrease resolution). But in most cases that wouldn't really help. About the timing difference between set term context and set term lua context: it is quite possible that metapost library is much faster than TikZ which uses TeX-based macros. TeX might be slower in calculations than metapost (which uses C for low level calculations) and TikZ is not optimized for drawing ten-thousand segments. And Hans really tried hard to optimize the code. Processing the output with ConTeXt is also at least ten times slower that outputting straight to PS or PDF and if you try ConTeXt MKII it is about two times slower than MKIV. You probably didn't have a chance to try the first implementations of ConTeXt terminal for gnuplot. It needed 10 minutes for 13 ordinary plots and it ran out of memory if I tried to plot 14 of them!!! (The reason was the usage of btex text etex constructs which lead to ConTeXt runs inside metapost runs inside ConTeXt runs, all doubled, maybe the labels were compile even four times, usually with a separate instance of ConTeXt for each plot.) Now compare that speed difference and the enormous optimization that Hans implemented back in 2006 ... The slow speed of TikZ is not something that you could do much about. There might be some tiny room for optimization in gnuplot-lua-tikz-common.tex, but hardly any. LuaTeX-based TikZ could be reimplemented and that would bring most benefits, but since Till almost-quit the project and since it works out-of-the-box with pdfTeX macros it is highly unlikely to happen. But yes, it would be nice if also ConTeXt terminal would be included. It still doesn't support raw images, but most other features are present.

It turns off text output from the png terminal without affecting any

epslatex terminals. I can post it again, or upload it to SourceForge
if it isn't there already.

Here is a brief list of changes to the gnuplot CVS version:
* support for ConTeXt and plain TeX
Hurray! Thanks a lot.
* removed dependencies for LaTeX packages other than TikZ
* needs TikZ Version = 2.0
* better support for saving terminal options with gnuplot 'save' command
* fixed overflow on negative coordinates that are outside of the crop box
* merged all recent patched from murphy-md and Ethan
Unfortunately it is the Context output that does not compile with the most
recent Context version I installed from TeXLive 2010 and the
http://tlcontrib.metatex.org/2010/ repository. But I remember it working
with an older version so I hope this can be fixed easily ...
Thanks, I just updated the CVS version of gnuplot with your files and gave it a
try: It works with minimals!

Feedback and patches welcome!
No patches I'm afraid. But feedback goes here:
1) The label text of the following key element takes the color of the preceding
key symbol. Minimal example:
set terminal lua tikz fulldoc size 15cm,7cm context
set output 'plot.tex'
set xrange [ 0 : 13 ]
f1(x)=sqrt(x)
f2(x)=sqrt(x*0.8)-3
plot f1(x) lc rgb 'blue', f2(x)
2) Negative axis labels are set with hyphen instead of proper minus sign, which
should be longer (see example above).
3) First I thought luatex hangs but then I noticed TikZ is awfully slow when
drawing plots with large amounts of data points (the tikzpicture had about 3000
lines). I can speed this up by reducing the size by invoking plot with:
plot gawk '(NR-1)%10 == 0 {print $0}' fileWithLotsOfData using [...]
I wonder if there is a smarter way to do this in gnuplot.
4) Is there a possibility to get rid of the vertical artifacts in filledcurves?
Note: the artifacts are only visible when plotting from data files.
set terminal lua tikz fulldoc size 15cm,7cm context
set output 'plot.tex'
plot gawk 'BEGIN {for (i = 1; i = 100; i++) {print i, 0.7*i, 0.8*i+50}}'
using 1:2:3 with filledcurve lc rgb 'black' t 'filled curve'
set xrange [ 0 : 13 ]
plot abs(x) with filledcurve xy=2,5
Best wishes,
Florian

Can you please send the same message to the gnuplot mailing list? I have sent the patch upstream once in 2006, but they had two arguments against including the patch: 1.) nobody from the development team was willing to install anything else but tetex to try it out (and the module doesn't work under tetex) 2.) they assumed that I was the only user The first point should hopefully be resolved by now (module should work under MikTeX or TeX Live out-of-the-box and hopefully TeX Live is enough widespread by now), but if anyone wants to have the module included, somebody else but me needs to write to the gnuplot mailing list and ask the developers if they are willing to include the patch. (By pointing them to https://github.com/mojca/gnuplot/blob/master/term/context.trm first.) I'm willing to upload the patch, but it makes no sense for me to regularly upload new patches to their feature-requests-and-bug-tracking system if they ignore them for ages ... I admit that the number of ConTeXt/Gnuplot users might be small, alone for the fact that the number of ConTeXt users (several thousand?) is much smaller than the number of LaTeX addicts, but I would be glad to see 20 users of metafont terminal when not even the output of metapost terminal is satisfactory (it could be improved considerably). Apart from that ... I was working with Peter Hedwig on the ConTeXt part of his lua/TikZ terminal (that has already been included in gnuplot). We got it running, with some issues like general font loading scheme, but the work was never polished to the end (stalled at some point). We could revive that thread as well. Github is currently down and It works here, but the main gnuplot code is located on fontforge (in CVS). Github only includes a patched version of gnuplot that contains context support. Mojca therefore cannot check if the code is included.
