Drawing Points

Points example

Copy and paste the following code, and save the file as s2points.c

#include <stdio.h>
#include <stdlib.h>
#include "s2plot.h"

int main(int argc, char *argv[])
{
   float xmin = -1, xmax = +1;          /* X data range */
   float ymin = -1, ymax = +1;          /* Y data range */
   float zmin = -1, zmax = +1;          /* Z data range */

   s2opend("/?",argc,argv);             /* Which S2PLOT device to open? */
   s2swin(xmin, xmax, ymin, ymax, zmin, zmax);  /* Set the display coordinates */

   s2show(1);                           /* Hand over to the display */

   return 1;
}

Compile using: cbuild.csh s2example<tt> and then run by typing <tt>s2example at the command prompt.
