x-axis: 0....5....1....1....2....2....3....3....4....4....5....5....6....6....7..

indicates time in sec/min or hrs of respective graph. It start from 0 & is increments of 5.

for eg. in seconds, it is:

5sec, 10sec,15sec,20sec,25sec....so on.

Y-axis is %util of cpu.

Maximum, peak or high water measurement of the CPU usage percentage during that particular time slice of the graph.
