This utility written in C, permit to display a distribution graph on terminal, the input MUST be provided as integer once for line. The utility permit to do a cat from logs (ie. containings execution time) and generate a terminal timing rapresentation as example. It's a real quick and dirty solution you will probably look for R for some more advanced statistical solution. But for a quick term solution is not so bad.
while true;
echo " TITLE GRAPH "
