color or symbol corresponds to each number by default. The commands below can be used to change
the default dashes, colors, or symbols.
\reconfigureplot{dashes}{〈pat 1 〉,...,〈pat n 〉}
\reconfigureplot{colors}{〈clr 1 〉,...,〈clr n 〉}
\reconfigureplot{symbols}{〈symb 1 〉,...,〈symb n 〉}
The first argument of \reconfigureplot is the rendering method to be changed: dashes,
colors or symbols. The second argument is a list of dash patterns, colors, or symbols. The dash
patterns should be names of patterns defined through the use of \dashpattern. The colors can be
any color names already known to METAPOST, or color names defined using \mfpdefinecolor.
The symbols can be any of those listed with the \plotsymbol command (see subsection 4.2.1), or
any known METAFONT path variable. The colors can also be METAPOST color constants or expressions,
and the symbols can be expressions of type path. In recent METAPOST these ‘colors’ can be
numeric (selecting gray), rgbcolor or cmykcolor. Within a mfpic environment, the changes made
are local to that environment. Outside, they affect all subsequent environments.
Using \reconfigureplot{colors} under the metafont option will have no effect, but may
produce an error from METAFONT unless the colors used conform to the guidelines in subsection
4.3.4. This also holds for \defaultplot{colors} (below).
\defaultplot{dashes}
\defaultplot{colors}
\defaultplot{symbols}
The command \defaultplot restores the built-in defaults for the indicated method of rendering
in \plotdata.
The commands \using, \mfpdatacomment and \sequence have the same meaning here (for
\plotdata) as they do for \datafile (above). The sequence numbering for \sequence starts over
with each new curve.
4.7 Labels and Captions.
4.7.1 SETTING TEXT
If option metafont is in effect macros \tlabel, \tlabels, \axislabels and \tcaption do not
affect the METAFONT file (〈file〉.mf) at all, but are added to the picture by TEX. If metapost is in
effect but mplabels is not, they do not affect the METAPOST file. In these cases, if these macros
are the only changes or additions to your document, there is no need to repeat the processing with
METAFONT or METAPOST nor the reprocessing with TEX in order to complete your TEX document.
\tlabel[〈just〉](〈x〉,〈y〉){〈labeltext〉}
\tlabel[〈just〉]{〈pair-list〉}{〈label text〉}
\tlabels{〈params 1 〉 〈params 2 〉 ...}
These place TEX text or math on the graph. The special form \tlabels (note the plural) essentially
just applies \tlabel to each set of parameters listed in its argument. That is, each 〈params k 〉
is a valid set of parameters for a \tlabel command. These can be separated by spaces, newlines,
or nothing at all. They should not be separated by blank lines.
The last required parameter is ordinary TEX text. The pair (〈x〉,〈y〉) gives the coordinates of a
point in the graph where the text will be placed. It may optionally be enclosed in braces, { and }. If
braces are used, any number of coordinate pairs may be listed, separated by commas. This is what
is meant by 〈pair-list〉 in the above syntax. If mplabels is in effect, the 〈pair-list〉 can be any list of
expressions recognized as a pair by METAPOST.
