From S2PLOT
s2sch
Set the character height in "arbitrary" units.
Prototype
void s2sch(float size);
Description
Set the character height in "arbitrary" units. The default character size is 1.0, corresponding to a character about 15 pixels in size. Changing the character height also changes the scale of tick marks and symbols.
