void zLabAng (angle) LABSET.C Level 1
 
int angle  The angle in degrees to which you wantW the z-axis labels to be rotated. The angle should be between -180 and 180. An angle of -90 gives upright labels.
 
zLabAng() sets the rotation angle for the z axis labels on 3-D plots. This routine sets the rotation angle for the z axis labels. See also xLabAng().
