This is a small script which utilizes the ping command and gnuplot to generate a graph.
./gnuplot-pingscript.sh
Enter the needed values when you are prompted to do so.
Another way to use the script is with arguments:
./gnuplot-pingscript.sh SERVER INTERVAL PING_COUNT PLOT_Y_START IMAGE_OUTPUT_HEIGHT IMAGE_OUTPUT_WIDTH
If you just want to generate the graph for a specific directory which
has a ping.txt file in it:
./gnuplot-pingscript.sh DIRECTORY PLOT_Y_START IMAGE_OUTPUT_HEIGHT IMAGE_OUTPUT_WIDTH
