Usage of the two main parameters

Let’s get an example of the time statistics parameter (will return mean, stdev, min and max of a statistics containing samples_number number of samples)

counter.timestats()

(0.01862650541, 7.4022264e-05, 0.01851450451, 0.01873824896)

Let’s get an example of the time array parameter (will return an array of timestamps of length samples_number)

counter.time_array()

array([0.01856394, 0.01875304, 0.01868165, 0.01846251, 0.01853304,
       0.01867947, 0.01863655, 0.0185761 , 0.01863821, 0.01867253,
       0.01866243])
