In the examples above the trend duration is one hour. The current time is 14:22. Note
that new data enters from the right and displaces older data to the left. When the
trend duration is changed, the right-hand time is held constant, but depending on the
scale setting, data is either displaced to the left or pulled in from the left.
The data update rate varies with the duration that has been selected.
(37.5 seconds
for the one hour mode and up to 15 minutes for the 24 hour mode.)

the graph represents the average data sample over a period of time as shown below:
