The graph is automatically rescaled so that the peak level
occupies the entire height of the graph. The graph update
interval is dependent on the width of the graph window and
the length of the graph.
During times of no lightning activity, occasional electrical
discharges may be detected. During these periods, the graph
will take on a “picket fence” appearance, with each picket
representing a single stroke or flash. This is normal and is not
indicative of a problem.
The Stroke Rate History window is very useful for spotting
trends in storm activity. A sudden increase in the flash rate
can be clearly seen. Also, a sudden surge in the fraction of
+CG strokes or –IC strokes becomes obvious, and can be an
indicator of a severe storm.
An image of the Stroke Rate History can be saved to a file at a
specified interval. See the Screen Captures dialog for details.
The contents of the graph window may be copied to the
clipboard for use in other applications by choosing the Copy
command from the Edit menu.
