s2svp
Set up the part of 3D space that is used for plotting.
Prototype
void s2svp(float x1, float x2, float y1, float y2, float z1, float z2);
Description
Set up the region of 3D space that is used for plotting. This is the "viewport" where graphics are drawn. The default values are [-1,+1] for all coordinates. A "fatal" error will occur if x1 > x2 or y1 > y2 or z1 > z2.

Code Example
#include <stdio.h>
#include <stdlib.h>
#include "s2plot.h"
int main(int argc, char *argv[])
{
s2opend("/?",argc, argv); /* Open the display */
s2svp(-1.,0., -1.,1., -1.,1.); /* First view port */
s2swin(-1.,1., -1.,1., -1.,1.); /* Set the window coordinates */
s2box("BCDET",0,0,"BCDET",0,0,"BCDET",0,0); /* Draw coordinate box */
s2sci(S2_PG_RED);
s2svp(0.5,1., -1.,1., -1.,1.); /* Second viewport */
s2swin(-1.,1., -1.,1., -1.,1.); /* Set the window coordinates */
s2box("BCDET",0,0,"BCDET",0,0,"BCDET",0,0); /* Draw coordinate box */
s2show(1); /* Open the s2plot window */
return 1;
