Section 7. Monitoring Data in Real-time
To clear the contents of the graphical x-y plot area while it is either stopped or
started, press the Clear button.
If the # Points per Field value is set to a very large number, and the
measurement rate of the datalogger is very fast (a period faster than 1 msec, for
example), the ability of the plot to display data in real-time may be reduced.
This is because points are displayed on the XY Plot contiguously as received
in time order from the datalogger. If you notice that the points being plotted
have fallen behind the real-time measurements, you can synchronize the
display back to the current measurement time by skipping over the points yet to
be plotted and returning to the newest points available. This is d
by
pressing the Sync Data button. The plot will be cleared and poin will begin
one
ts
to be displayed using the newest data arriving from the datalogger. In some
instances you can alleviate the lagging condition instead by using a smaller
value for the # Points per Field setting.
