 Minimal Graphical IPV4 Ping Tool.  (also comes with searchnet, like nmap but smaller and simpler).  It uses rawdraw so it is OS independent.
 
-Usage: cnping [IP address] [seconds between pings (decimal OK)] [additional size to increase]
+Usage: cnping [host] [period] [extra size] [y-axis scaling]
