| |
| <table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td> |
| |
| <i>Graph</i> with no options takes pairs of numbers from the standard |
| input as abscissas (<i>x</i>-values) and ordinates (<i>y</i>-values) of a graph. |
| Successive points are connected by straight lines. The graph is |
| encoded on the standard output for display by <a href="../man1/plot.html"><i>plot</i>(1)</a> filters. |
| |
| <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> |
| |
| If an ordinate is followed by a nonnumeric string, that string |
| is printed as a label beginning on the point. Labels may be surrounded |
| with quotes <tt><font size=+1>" "</font></tt> in which case they may be empty or contain blanks |
| and numbers; labels never contain newlines. |
| <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> |
| |
| The following options are recognized, each as a separate argument.<br> |
| <tt><font size=+1>−a</font></tt> Supply abscissas automatically; no <i>x</i>-values appear in the input. |
| Spacing is given by the next argument (default 1). A second optional |
| argument is the starting point for automatic abscissas (default |
| 0, or 1 with a log scale in <i>x</i>, or the lower limit given by <tt><font size=+1>−x</font></tt>).<br> |
| <tt><font size=+1>−b</font></tt> Break (disconnect) the graph after each label in the input.<br> |
| <tt><font size=+1>−c</font></tt> Character string given by next argument is default label for |
| each point.<br> |
| <tt><font size=+1>−g</font></tt> Next argument is grid style, 0 no grid, 1 frame with ticks, |
| 2 full grid (default).<br> |
| <tt><font size=+1>−l</font></tt> Next argument is a legend to title the graph. Grid ranges are |
| automatically printed as part of the title unless a <tt><font size=+1>−s</font></tt> option |
| is present.<br> |
| <tt><font size=+1>−m</font></tt> Next argument is mode (style) of connecting lines: 0 disconnected, |
| 1 connected. Some devices give distinguishable line styles for |
| other small integers. Mode –1 (default) begins with style 1 and |
| rotates styles for successive curves under option <tt><font size=+1>−o</font></tt>.<br> |
| <tt><font size=+1>−o</font></tt> (Overlay.) The ordinates for <i>n</i> superposed curves appear in the |
| input with each abscissa value. The next argument is <i>n</i>.<br> |
| <tt><font size=+1>−s</font></tt> Save screen; no new page for this graph.<br> |
| <tt><font size=+1>−x l</font></tt>If <tt><font size=+1>l</font></tt> is present, <i>x</i>-axis is logarithmic. Next 1 (or 2) arguments |
| are lower (and upper) <i>x</i> limits. Third argument, if present, is |
| grid spacing on <i>x</i> axis. Normally these quantities are determined |
| automatically.<br> |
| <tt><font size=+1>−y l</font></tt>Similarly for <i>y</i>.<br> |
| <tt><font size=+1>−e</font></tt> Make automatically determined <i>x</i> and <i>y</i> scales equal.<br> |
| <tt><font size=+1>−h</font></tt> Next argument is fraction of space for height.<br> |
| <tt><font size=+1>−w</font></tt> Similarly for width.<br> |
| <tt><font size=+1>−r</font></tt> Next argument is fraction of space to move right before plotting.<br> |
| <tt><font size=+1>−u</font></tt> Similarly to move up before plotting.<br> |
| <tt><font size=+1>−t</font></tt> Transpose horizontal and vertical axes. (Option <tt><font size=+1>−a</font></tt> now applies |
| to the vertical axis.) |
| <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> |
| |
| If a specified lower limit exceeds the upper limit, the axis is |
| reversed.<br> |

| Segments that run out of bounds are dropped, not windowed. Logarithmic |
| axes may not be reversed. Option <tt><font size=+1>−e</font></tt> actually makes automatic limits, |
| rather than automatic scaling, equal.<br> |
