first column channel number, second direction (outgoing/incoming), third field start date/time, fourth end date/time , last 1 duration of conversation. possible plot diagram similar gantt diagram date/time on x axis (taken data) , on y axis every line present each channel each converstion present segment on line?

you can use vectors plotting style draw information. using arrowstyle variable can use different appearances incoming , outcoming calls:

set ylabel 'channel number' set xlabel 'time'  incoming = 0 set style arrow 1 lc rgb 'green' lw 2 size char 0.5,90 heads set style arrow 2 lc rgb 'red' lw 2 size char 0.5,90 heads  set xdata time set timefmt '%y/%m/%d %h:%m:%s'  plot 'data.txt' using 3:1:(strptime('%h:%m:%s', strcol(7))):(0):($2 == incoming ? 1 : 2) vectors arrowstyle variable notitle
