.\" SCCSID: @(#)graph.1g	8.1	9/11/90.TH graph 1g.SH Namegraph \- draw a graph.SH Syntax.B graph[\|\fIoption...\fR\|] .SH Description.NXA "graph command" "spline command".NXA "graph command" "plot command".NXR "graph" "drawing".NXR "graph command"The.PN graphcommand with no options takes pairs of numbers from thestandard input as abscissas andordinates of a graph.Successive points are connected by straight lines.The graph is encoded on the standard outputfor display by the .MS plot 1gfilters..PPIf the coordinates of a point are followed bya nonnumeric string, that string is printed as alabel beginning on the point.Labels may be surrounded with quotes "...", inwhich case they may be empty or contain blanksand numbers;labels never contain new lines..PPA legend indicating grid range is producedwith a grid unless the.B \-soption is present..PPIf a specified lower limit exceeds the upper limit,the axisis reversed..SH Options.NXR "graph command" "options".IP \fB\-a\fR 12Supplies abscissas automatically and uses next two arguments to set spacing andstarting point.Spacing is given by the nextargument (default 1).A second optional argument is the starting point forautomatic abscissas (default 0 or lower limit given by.BR \-x )..IP \fB\-b\fR Breaks graph after each label in the input..IP \fB\-c\fR Uses specified string (next argument) as label..IP \fB\-g\fR Uses specified number (next argument) in setting upgrid style:  0 (no grid), 1 (frame with ticks),and 2 (full grid).  Default is 2..IP \fB\-h\fR Uses specified number (next argument) as fraction of space for height..IP \fB\-l\fR Uses specified string (next argument) as graph label. .IP \fB\-m\fR Uses specified number (next argument) in setting up line mode:  0(disconnected) and 1 (connected).  Default is 1..IP \fB\-r\fR Uses specified number (next argument) as fraction of space to right beforeplotting..IP \fB\-s\fR Saves screen (no erase) before plotting..IP \fB\-t\fR Transposes vertical and horizontal axes..IP \fB\-u\fR Uses specified number (next argument) as fraction of space to move up before plotting..IP \fB\-w\fR Uses specified number (next argument) as fraction of space for width..IP "\fB\-x\fR [ \fBl\fR ]" Determines x axis logarithmically.  Next two arguments after .B ldetermine lower and upper.I xlimits respectively.  The third argument determines grid spacing on .I xaxis..IP "\fB\-y\fR [ \fBl\fR ]" Same as .B xbut for .B yaxis..SH Restrictions.NXR "graph command" "restricted"The.PN graphcommand stores all points internally and drops those for whichthere is not room..spSegments that run out of bounds are dropped, not windowed..spLogarithmic axes may not be reversed..SH See Alsoplot(1g), spline(1g)
