graph
Examplesgraph
graph
reads in ascii data. Most often, the data is in the form
of pairs of x and y values:
0.0 0.0 1.0 0.2 2.0 0.0 3.0 0.4 4.0 0.2 5.0 0.6
You can add labels to specific data points by appending a string after the y coordinate. The label ends at the end of the line:
3.0 0.4 this is a label for point (3.0, 0.4).
Using the `-b' option, you can put more than one data set in the input as long as each is monotonic in x values and decreases from the end of one set to the start of the next:
0.0 0.0 first data set 2.0 0.0 4.0 0.2 0.0 0.1 second data set 2.0 0.2 4.0 0.3
If your data contains only y values which are equally sampled along the x axis, you can use the `-a' option to specify the x axis values implicitly.
0.0 0.1 0.2 label for point (2.0, 0.2) 0.3 0.2 0.3
The command
graph -h .4 -w .4 -r .1 -u .1 < ascii_data_file_1 > plot_file
will put a single box containing the plot in the lower left hand quarter of the page. You can add another plot to the upper left hand corner of the page using the command
graph -h .4 -w .4 -r .1 -u .6 < ascii_data_file_2 >> plot_file
Likewise you can add plots to the right hand side of the page using
graph -h .4 -w .4 -r .6 -u .1 < ascii_data_file_3 >> plot_file graph -h .4 -w .4 -r .6 -u .6 < ascii_data_file_4 >> plot_file
The tick marks can be moved inside the box and labels moved to the opposite sides using
graph -T -.005 -x T -y L < ascii_data_file >> plot_file
plot2ps
Utility
plot2ps
is a utility for converting Unix plot files into
postscript. The plot2ps
utility reads plotting commands from
named files or the standard input and writes postscript to the standard
output. You can then print the postscript output on a printer, or edit
it using the idraw
graphics editor. You can also easily include
the output in LaTeX documents using the dvi2ps
utility and the
LaTeX command psfig
.
The source code and documentation for plot2ps
and a more complete
description of this are available via anonymous ftp from qed.rice.edu
(128.42.4.38) in the directory `/pub'.
