OK, that's a good point, and I fully agree with it. It's only that I would probably use something like that for really simple, short, one-page documents, where I would be concerned about the speed I need to come to a solution, not with the speed of document processing - half a second more or less. This was in my case also a one page document but I created over hundret full page graphics (needed for fieldstacks) and it is a real problem in this case, the other problem for this solution was, I had to pass dozen graphic position to Metapost and it was easier to do the whole work within TeX and use Metapost only to create the needed graphics one and reuse them. With the route tex - .plt file - gnuplot - tex (metafun) - metapost (- mpto or \sometxt) - pdf, which I frequently use, the situation is much much worse, but it's still acceptable. ConTeXt became at least 10 times faster during the last three or four years. (Or at least that's my impression.) I don't use gnuplot and I think a lua driven Tikz should solve this in the future, calculate the graphs with lua definition and draw the graphics with TeX macros. You should also replace the fullcircle with drawdot in your example, drawdot renders better on screen and looks better. Thanks. I always use fill fullcircle for some reason. Perhaps I should changle my habit :) Sorry, my fault. What I meant was the difference between draw point and drawpoint point where the first should be replaced in this situation with the later, fullcircle produce nice circles and Donald Knuth took care about this.

You introduce spurious spaces (line break sometimes adds a space) in
you loops. See

Remove the comment sign behind the inner loop and see what happens.

Hi,
there is smarter and better solution than loop for doing this work,
you can use leaders. I prefer myself xledaers in this example (alternative b).
\defineoverlay[PageGrid][\PageGrid]
\setupbackgrounds[page][background=PageGrid,offset=5mm]
\starttext
% alternative a:
\def\PageGrid
{\setbox\scratchbox\hbox to\dimexpr\paperwidth-1cm\relax
{\leaders\hbox to 1cm{\hss$\bullet$\hss}\hfill}%
\vbox to\dimexpr\paperheight-1cm\relax
{\leaders\vbox to 1cm{\vss\box\scratchbox\vss}\vfill}}
\page[empty]

\def\PageGrid
{\setbox\scratchbox\hbox to\dimexpr\paperwidth-1cm\relax

You introduce spurious spaces (line break sometimes adds a space) in you loops. See ... Yes, you're right. A programmer, I tend to think that white space is always good for readability.
