void fntchg(symbol) FNTPLT.C Level 13
char symbol The ASCII font change symbol as defined by the argument char esc# in the call to font().
Axes drawing routines such as graf() use the currently active font to calculate the spacings of labels and to number the axes. It is best to select the font you are going to use before any calls to the axes drawing routines. Within strings, fonts are changed by inserting the font escape characters, and therefore this routine usually is not needed.
