plssym — Set symbol size
This sets up the size of all subsequent symbols drawn by plpoin(3plplot) and plsym(3plplot). The actual height of a symbol is the product of the default symbol size and a scaling factor as for the character height.
Redacted form: plssym(def, scale)
This function is used in example 29.
- def (PLFLT(3plplot), input)
The default height of a symbol in millimeters, should be set to zero if the default height is to remain unchanged.
- scale (PLFLT(3plplot), input)
Scale factor to be applied to default to get actual symbol height.
