==s2box== Draw a labelled box around the world space. ==Prototype== <code><pre> void s2box(char *xopt, float xtick, int nxsub, char *yopt, float ytick, int nysub, char *zopt, float ztick, int nzsub); </pre></code> ==Description== Draw a labelled box around the world space. Arguments xtick, ytick and ztick specify the major tick intervals on each axis (0.0 means let S2PLOT figure out the "best" value/s); nxsub, nysub and nzsub indicate how many subdivisions the major intervals should comprise and are ignored when S2PLOT is determining major intervals itself. If nxsub, nysub or nzsub are 0, then they are automatically determined. xopt is a character string, with any of the following flags: * B = draw front bottom (-Y,-Z) edge * C = draw front top (-Y,+Z) edge * D = draw back bottom (+Y,-Z) edge * E = draw back top (+Y,+Z) edge * T = draw major tick marks * S = draw minor tick marks [not yet implemented] * M = numeric labels in conventional location/s * N = numeric labels in non-conventional location/s * O = draw labels on an opaque panel so they are never seen in reverse - this is always done if both M and N options are requested * Q = make panel larger to fit axis titles drawn by s2lab function * G = draw grid lines at major tick intervals * L = written label is 10^(coordval), ie. logarithmic labels * 1 = force decimal labels (this is default: redundant option) * 2 = force exponential (scientific notation) labels yopt is a character string as for xopt, but with following changes: * B = draw bottom left (-Z,-X) edge * C = draw bottom right (-Z,+X) edge * D = draw top left (+Z,-X) edge * E = draw top right (+Z,+X) edge zopt is a character string as for xopt, but with following changes: * B = draw left front (-X,-Y) edge * C = draw right front (-X,+Y) edge * D = draw left back (+X,-Y) edge * E = draw right back (+X,+Y) edge == See Also == <table> <tr><td>[[Function:s2lab | s2lab ]]</td><td>Draw labels along the edges of bounding box. </td></tr> </table> ==PGPLOT Equivalent== [http://www.astro.caltech.edu/~tjp/pgplot/subroutines.html#PGBOX PGBOX] ==Code Example== <code><pre> #include <stdio.h> #include <stdlib.h> #include "s2plot.h" int main(int argc, char *argv[]) { char xopt[] = "BCDETMNOPQ"; char yopt[] = "BCDETMNOPQ"; char zopt[] = "BCDETMNOPQ"; s2opend("/?",argc, argv); /* Open the display */ s2swin(-1.,1., -1.,1., -1.,1.); /* Set the window coordinates */ s2box(xopt, 0,0, yopt, 0,0, zopt, 0,0); /* Draw the coordinate box */ s2lab("X-axis","Y-axis","Z-axis","Plot"); /* Write some labels */ s2show(1); /* Open the s2plot window */ return 1; } </pre></code> [[S2PLOT:Function List | Back]] to S2PLOT function list. __NOTOC__ __NOEDITSECTION__
