This directory holds the code for the 'plotcsv' program.  This program
is meant to be used to view stage versus time from an ANUGA *.csv data
file and compare a similar graph from another file as a quality assurance
step.

Usage:  plotcsv.py <options> <filename>
where <filename> is the path to the data file to plot
  and <options>  is zero or more of:
                   -x <datacol> where <datacol> is a column specifier,
                   -y <datacol>     either a number or a header string
                   -v <range>   force a range in Y axis values, of the form
                                    <min>,<max>, eq, "-5,10"
                   -h           prints this help

The <datacol> values above may be either a column number (starting from the
left at column 0) or a string that must match one of the column header
strings in the first line of the CSV file.  If the '-x' or '-y' options
x are not supplied then the X column is assumed to be column 0 and the Y
column is assumed to be column 1.

The '-v' option can be used to force a max/min range in the Y axis to allow
easier comparison of two graphs that would otherwise autoscale the Y axis
differently.

Ideally, the program will stop running but leave the plot window on the screen,
to be closed by the user, but this doesn't appear possible with matplotlib.

For example, try:
    plotcsv.py -x time -y stage test.csv
or
    plotcsv.py -x time -y stage -v -2,25 test.csv
or
    plotcsv.py -x time -y depth test.csv
or
    plotcsv.py -x 0 -y 1 test.csv
or even
    plotcsv.py test.csv
