.TH DATAPLOT 1 "March 5, 1985" "UNIX|STAT 5.0" "UNIX User's Manual"
.SH NAME
dataplot \- plot paired data
.SH SYNOPSIS
.B dataplot
[options]
.SH DESCRIPTION
.PP
.I dataplot
makes simple plots of paired (X-Y) data for character terminals and printers.
.I dataplot
reads a two column input from the standard input
and prints to the standard output.
.SH OPTIONS
.P
All options can be specified for the X or Y axis.
So all option values begin with the letter x or y
and are immediately followed by a value.
See the examples.
.TP 
.B "-b [xy]char"
Border character.
If unspecified,
a standard border is plotted.
.TP
.B "-m [xy]min"
Minimum value plotted on the axis.
If unspecified, the minimum data value is used.
.TP
.B "-M [xy]max"
Maximum value plotted on the axis.
If unspecified, the maximum data value is used.
.TP
.B "-s [xy]size"
Plot size.
If unspecified, a plot of 60 columns by 20 rows is printed.
This is ideal for most terminal screens.
.TP
.B "-n [xy]name"
Axis names.
.SH EXAMPLES
Name the axes.
.ce
dataplot -n xHeight -n yWeight
Change the size of the plot to 10 x 50.
.ce
dataplot -s x10 -s y50
Set the plot region so that the x axis is plotted from 0 to 100
and the y axis is plotted from -10 to 10.
.ce
dataplot -m x0 -M x100 -m y-10 -M y10
.SH LIMITATIONS
For plots, the number of points is limited to some large number,
perhaps 1000.
The maximum plot dimensions are 100 x 100.
The minimum plot dimensions are 10 x 10.
.SH DIAGNOSTICS
Points outside the plotting region cause error messages.
