To plot a graph, set the sampling period for the measurement data.
This graph allows the plotting of 60 data items on one graduation on the time axis. So, if
you set a ten-second sampling period, one graduation corresponds to 600 seconds
(Figure 10.5). The allowable sampling periods range from 1 to 30 seconds. If you set a
one-second sampling period, the axis of the abscissas then corresponds to five minutes.
If you set it to 30 seconds, the axis of the abscissas then corresponds to 150 minutes.
