NAME
----
	tcsv2png - data visualization of csv data with a time column.

SYNPSIS
-------
	tcsv2png [Options] CSV_FILE [COL0 [COLi ...]]

DESCRIPTION 
-----------
	tcsv2png uses gnuplot to convert a csv file with a time column
	format %H:%m:%S into a chart in png format.

	It scales the data to show all of the data sets in the same
	png chart.

        You can select the columns of interest. The tool uses gnuplot
        to generate the chart, so you can customize the script to your
        need.

        CSV_FILE: a csv file with TAB fields separator
        COL0:     the column indice that contains the time formated H:M:S
        COLi:     column indice to plot

        Note that column indice starts with 0 and that the first line
        should contains columns headers.
