plpoin
PLPOIN(3plplot) PLplot API PLPOIN(3plplot)
NAME
plpoin - Plot a glyph at the specified points
SYNOPSIS
plpoin(n, x, y, code)
DESCRIPTION
Plot a glyph at the specified points. (This function is largely superseded by plstring(3plplot) which gives access to many[!] more
glyphs.) code=-1 means try to just draw a point. Right now it's just a move and a draw at the same place. Not ideal, since a sufficiently
intelligent output device may optimize it away, or there may be faster ways of doing it. This is OK for now, though, and offers a 4X
speedup over drawing a Hershey font "point" (which is actually diamond shaped and therefore takes 4 strokes to draw). If 0 < code < 32,
then a useful (but small subset) of Hershey symbols is plotted. If 32 <= code <= 127 the corresponding printable ASCII character is plot-
ted.
Redacted form: plpoin(x, y, code)
This function is used in examples 1,6,14,21,29.
ARGUMENTS
n (PLINT, input)
Number of points in the x and y arrays.
x (PLFLT *, input)
Pointer to an array with X coordinates of points.
y (PLFLT *, input)
Pointer to an array with Y coordinates of points.
code (PLINT, input)
Hershey symbol code (in "ascii-indexed" form with -1 <= code <= 127) corresponding to a glyph to be plotted at each of the n points.
