Data visualization of csv data with a time column.




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


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


tcsv2png uses gnuplot to convert a csv file with a time column (HH:MM:SS format) into a png chart.

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

You can select the columns of interest. You can customize the generated gnuplot script to your need.

CSV_FILE: a csv file with TAB or semicolon 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.


tcsv2png requires gnuplot.


sudo easy_install tcsv2png
