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
