It's the same error as trying to “plot” the MP code 1; MetaPost is confused since it has no idea what to do with that number and tells you so. Since MP can handle more than just numbers, you get a slightly more general error message that talks about an “expression” rather than a “number.” What you can do is something like \starttext \startusableMPgraphic{sin} for x := 0 step 0.6282 until 6.282: drawdot(10*x, 10*sin(x)) withpen pencircle scaled 1pt; endfor \stopusableMPgraphic \useMPgraphic{sin} \stoptext Or, you can use the fact that in MetaPost you can build up an expression within a for loop as follows: \starttext \startusableMPgraphic{sin} draw (0,0) for x := 0 step 0.2 until 6.282: ..(10*x, 10*sin(x)) endfor; \stopusableMPgraphic \useMPgraphic{sin} \stoptext I think it really helps with MP programming to understand this type of loops.

MetaPost is not really a function plotter. So, yes, you have to use some sort of loop, although there may be some predefined macros hiding them.

Not really, that causes all sorts of problems when trying to get the same font all over the place etc. But you might be interested (assuming you can read or at least decipher French) in the pages at http://melusine.eu.org/syracuse/metapost/galeries/ – complete code included.

I do something like: set terminal latex set output "file.tex" set title '\bf My wonderful function $sin(\omega t)$' set xlabel '$t\ \rm[s]$' set ylabel '$A$' plot sin(x) and then "\input file" inside of the main LaTeX file. Gnuplot cannot make output in ConTeXt (yet), but perhaps you can include the resulting PDFs in your ConTeXt source. (Gnuplot is one of the very few examples where I still use LaTeX.) You can also output the (ConTeXt-friendly) metapost (with set terminal), but you lose on quality. Mojca ^ permalink raw reply [flat|nested] 26+ messages in thread

Drawing only the points results in a reasonably small file. > btw, is it really that difficult to use gnuplot output in context? No. A file context.trm (http://cvs.sourceforge.net/viewcvs.py/gnuplot/gnuplot/term/) should be written by modifiying the postscript/metapost/latex.trm and perhaps some layer should be added in ConTeXt for \startgnuplot ... \stopgnuplot. Metapost can already be used, perhaps only some interaction with ConTeXt is missing (setting point shapes & colors, fonts, ... somewhere at the beginning or in a separate style file). To answer Christophers's and Alexander's question about quality of metapost output: I guess I mixed it up with pslatex when I was talking about the output quality. You can't express it in percentage. See http://pub.mojca.org/tex/gnuplot/trlin.pdf for an example graph with latex/pslatex/mp as rendering terminal. The second example could be easily manually tuned a bit afterwards. Linewidths & typesetting in general is a bit worse (from my point of view), but there's no such quality loss as if you use PNGs. Mojca ^ permalink raw reply [flat|nested] 26+ messages in thread

You could also try PSTricks: \usemodule[pstric] \starttext \startPSTRICKS \psplot[plotpoints=100]{0}{1}{x 360 mul sin} \stopPSTRICKS \stoptext Cheers, Peter -- http://pmrb.free.fr/contact/ ^ permalink raw reply [flat|nested] 26+ messages in thread
