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
