Convert time-dependent tabular 2D data to executable gnuplot scripts

$ usageinfo [OPTION]... INFILE

• --man

  Print the manual page and exit.

• --help

  Print a brief help message and exit.

Customize how data is read in.

• --sep = value

  Set separation character for plain text files.

• --sheet = value

  Set sheet number for spreadsheet files (default: 1).

• --column = abscol,ordcol

  Set numbers of abcissa column (default: 1) and ordinate column (default: 2) separated by a comma.

• --dtfmt = datespec

  Set date specifier accordint to strftime.

Customize how data is output.

• -o, --out = filename

  Write output to specified output file instead of STDOUT.

• -t, --title = string

  Use specific Gnuplot title.

• --ylabel = value

  Use specific Gnuplot label for ordinate axis (default: undef).

• --xformat = value

  Use specific Gnuplot label for ordinate tics (default: undef).

• --yformat = value

  Uses specific Gnuplot label for ordinate tics (default: undef).

• --yrange = value

  Use specific Gnuplot range for ordinate axis (default: undef).

• -c, --color = colorspec

  Use specific Gnuplot color.

• -r, --rate = ratespec

  Show first derivative of ordinate values with respect to ratespec. Available options are: year, month, week, day, hour, min, sec. Alternatively, a custom period can be specified in seconds.

• -s, --scale = num

  Scale ordinate values by factor num (default: 1).

• --term = value

  Use sepecific Gnuplot terminal and option (default: undef).

• -g, --gnuplot [= command ]

  Run gnuplot on output and raise X window. Set terminal to qt. Submitting the command is optional. If no command is defined, the system will try to auto-detect the location of gnuplot.

Customize how data is split.

• -p, --period = string

  Split data with respect to periods into datasets. Avaliable options are year, month, week, day, hour (default: year).

• -i, --interpolation = string

  Specify interpolation method for period boundaries. Available options are: C, C (default: cspline).

• -m, --max = num

  Limit output to latest num datasets. Set to zero to include all available datasets (default: 0).

• --reset

  Reset ordinate values to zero at the start of each dataset.

• Math::Derivative - Numeric 1st and 2nd order differentiation
• Math::Spline - Cubic Spline Interpolation of data
• Spreadsheet::Read::Simple - Simple parsing of spreadsheets
• Time::Piece - Object Oriented time objects
• Time::Seconds - API to convert seconds to other data values
