How do I change fonts in vplot graphics?
The collection of fonts in Vplot is small and goes back to so-called "Hershey fonts" (created originally by Dr. A.V. Hershey at the U. S. National Bureau of Standards).
You can use \F# directives to switch between different fonts.
In general, there are two sorts of escape sequences, those that take an argument and those that do not. Here is a complete list of escape sequences that do not take an argument:
The following escape sequences take an integer argument immediately after, with a required space after the integer to delineate the end. This space is not printed.
The following example is from rsf/rsf/sfgraph:
The line to create this title is
You can find a set of tests for different fonts in pens/tests:

roman duplex
roman complex

You can use \F# directives to switch between different fonts.
In general, there are two sorts of escape sequences, those that take an argument and those that do not. Here is a complete list of escape sequences that do not take an argument:
- \> Advance one interletter space
- \< Back up one interletter space
- \^Raise one half of a capital letter height
- \_ Lower one half of a capital letter height
- \g Continue processing text, but don't actually print it ("ghostify it").
This is useful if you want to leave space to go back and add something by hand. - \G Start printing text again ("deghostify")
- \n Newline
- \h Backspace (control-h also works) back up over the last character
- \- Does nothing; used to prevent a group of characters from being formed into a ligature.
- \\ Print a backslash
The following escape sequences take an integer argument immediately after, with a required space after the integer to delineate the end. This space is not printed.
- \s# Size change. Change to # percent of the size set in the text vplot. \s100 restores the default height.
- \f# Add # to current fatness. Goes out of effect when text printing is finished.
- \F# Switch to font number #. (-1 restores the default font).
- \k# Move by # space widths to the right (in percent; 100 = one space width). Negative numbers are allowed (moves left).
- \r# Move up # character heights (in percent; 100 = the height of a standard capital letter). Negative numbers are allowed (moves down).
- \v# Print ASCII character number # in the current font, stripping it of any special meaning. This and ligatures are the only way that glyphs numbered greater than 255 are available.
- \c# Switch to color number #. \c-1 restores the current drawing color. Vplot's current drawing color is not changed by changing the color inside text.
- \m# Save current position in register number #.
- \M# Restore position saved in register number #.
The following example is from rsf/rsf/sfgraph:
The line to create this title is
title="\s100 \F11 Polinom CHebysheva + \F3 T\_\s75 n\^\s100 (cos \F10 q) = \F3 cos n\F10 q".

Thank you very much Sergey! Very useful post I must say when one needs math symbols in labels :)
Hallo Sergey!
Thank you for this posting!
I try to use the ".vplot_font"-files, but I do not understand what is the definition from 2 numbers after "e"-letter like this:
e 10 11 f
I can to use the coordinates and I can to paint with them, but what are the 2 numbers?
I think a one from them is a letter-width, but which from them?
I need the documentation from ".vplot_font"-files. Where can I find it?

Доброго времени Ñуток Сергей!
СпаÑибо тебе за предоÑтавленную здеÑÑŒ информацию и ÑÑылки.
Я пробую разобратьÑÑ Ñо Ñтруктурой ".vplot_font"-файлов и не могу никак понÑÑ‚ÑŒ
что означают две цифры поÑле буквы "е" в них, например:
e 10 11 f
Я могу пользоватьÑÑ ÐºÐ¾Ð¾Ñ€Ð´Ð¸Ð½Ð°Ñ‚Ð°Ð¼Ð¸ и у Ð¼ÐµÐ½Ñ Ð¿Ð¾Ð»ÑƒÑ‡Ð°ÐµÑ‚ÑÑ Ñ€Ð¸Ñовать буквы, но Ñ Ð½Ðµ знаю что значат Ñти 2 цифры.
Я думаю что одна из них означает ширину файла, но ÐºÐ°ÐºÐ°Ñ Ð¸Ð· них?
Об Ñтом шрифте Ñ ÑƒÐ·Ð½Ð°Ð» Ñлучайно и получил только буквы латинÑкого алфавита.
Координаты в том шрифте ÑтоÑÑ‚ немного выше чем в Ñтих, Ñ…Ð¾Ñ‚Ñ Ð¾Ð½Ð¸ тоже на оÑнове Hershey
и Ñ Ð²Ð¾Ñ‚ думаю может здеÑÑŒ ещё какие-то оÑобенноÑти нужно учитывать при прориÑовке?
Очень хочетÑÑ Ð½Ð°Ð¹Ñ‚Ð¸ документацию к ".vplot_font"-файлам. Где её можно найти?
Заранее большое ÑпаÑибо!
