NAME

       plotit - experiment data visualization

SYNOPSIS

       plotit -w FILE
       plotit [-lp] -q FILE [FILE]...
       plotit [-lp] Y FILE [FILE...]
       plotit [-lp] X Y FILE [FILE...]

DESCRIPTION

       The plotit program is a simple plotting program which can draw line plots and stripcharts using a command
       language  similar  to  that  of  gnuplot.   It  can also make quick plots of multiple data files from the
       command-line.  Wildcards may be used in the file names.

       The program takes optional expressions which can be used to  manipulate  data  columns  before  plotting.
       Expressions  may  be  as  simple  as  the designation of a column to be plotted or may contain arithmetic
       expressions and functions.  In the latter case the espression must be enclosed in  'single'  or  "double"
       quotation marks. Column numbers are designated by the at-sign character (@).  A single expression is used
       for the Y axis of the plot.

OPTIONS

       -h, --help
              Print the usage and exit.

       --version
              Print the version number and exit.

       -w     Watch  the  input  file  for commands to stripchart, or wait to read all of stdin before plotting.
              Only one file or - for stdin may be specified with this option.  No other options may be  used  in
              conjuction with this option.

       -q     Plot the first and second columns of each file.

       -l     Plot with lines.

       -p     Plot with points.

EXAMPLES

       Plot the second column versus the first of all three files with lines only.

              plotit -lq file1.dat file2.dat file3.dat

       Plot the quotient of the third column and the second column versus the first column of all files matching
       the pattern using points only.

              plotit -p '@3/@2' file??.dat

       Plot  the  natural  log  of  the  second column divided by the third column versus the fourth column.  By
       default these data are plotted with both lines and points.

              plotit @4 'log(@2/@3)' file.dat
