Without adding that line, the whole figure does not appear at all in the .dvi file, but it does appear in the .ps file together with all three labels correctly shown. In any case, I insert my mp file. The macros were copied from J. Hobby's manual pp. 45 and 46, because I didn't know (and still don't know) how simply draw an angle. As far as the question ``xdvi or ps?'', there's something more that for me is definitely in xdvi's favour: I do a large use of hyper referencies, that, as far as I know, work in the .dvi file but not in the final .ps file, which is the step just before the document printing.

To have hyper-references in the postscript file, run dvips with the proper option. I think it's -z, but you can learn for sure with dvips --help or read the docs (dvips.). I've written the following a number of times (both to this list and to c.t.t, so perhaps a search of the archives will find it) but I guess it bears repeating: 1. MetaPost never adds fonts to the ps file it creates, It only adds a call by name. 2. Without prologues, the name it uses is the .tfm file name, which is almost always wrong. (But good ebough for dvips to figure out and embed the fonts.) 3. With prologues > 0, it consults psfonts.map (the same file as dvips uses) but all it does is translate the .tfm file name to the correct PS font name. It still doesn't embed the font. 4. Most TeX fonts are not installed for use by GhostScript. So trying to view a metapost figure with fonts directly in GS won't work if it contains, for example, CMR10. It either fails outright or Courier is substituted as a default. 5. When xdvi, windvi, Yap (and other dvi viewers) find ps graphics included, they pass it on to GS to render into some graphic format the program's display engine can handle. So the same problems occur as in point 4 above. 6. To use a font with GS, one needs only (a) the font file (.pfb), (b) the font names in the .ps file (prologues), and (c) a Fontmap file that translates the font name into filename, OR the .pfb file has to be in a directory GS has been configured to search for fonts. There exists such a Fontmap file, (Fontmap.cm) on the net somewhere, but it has only the .pfb file _names_, not their paths. Therefore you either have to edit it extensively, or copy all the .pfb files into a directory GS searches. Unfortunately, GS does not seem to permit subdirectory recursion in its search paths. The conclusion: I use only dvips and pdftex when I have a file with Metapost figures. The hassle of getting TeX+xdvi+GS+Metapost to work together is not worth it, I don't even try, and I don't understand those who insist on trying to make it happen. I have to edit-compile-preview tex files containing metapost figures hundreds of times a year. These files might have a hundred figures in them. That's tens of thousands of times my dvi viewer would have to call GS. Instead, I use a previewer that is built to handle Postsctipt and cut out the middle man.

This does produce a repeating label but not cleanly along the x axis (it prints on top of the lower frame line) and not synchronized with each tick. If I could somehow position the entire line properly I could conceivably try to match each value with ticks (though that would require a lot of trial and error and does not seem like a flexible solution). I was originally asking whether MetaPost can simply handle (say, year/month or year/month/day) dates as the x-coordinate value within the dataset file; that is, something like 1999/11 10.6 1999/12 12.1 2000/01 5.4 . . . 2000/12 11.3 Failing that, however, I can try employing a calculation like Brian's to assign dates to tickpoints on the graph. I'm able to assign limited types of values to tickpoints using the grid.bot(format("%f",k), x) construction (as demonstrated in Hobby's graph manual); so it seems like this should permit me to loop through numeric year/month combinations. I haven't been able to combine two integer values in the k position above as in Brian's example, though: & is not recognized as a concatenation operator in the grid.
