The function updates the Data Statistics table and the plots. To perform
the updates, it calls the
refreshDisplays function twice, which is a
custom function added to the G UI code file. In between the two calls, the
refreshDisplays function retrieves row indices for the current selection
from the
currSelection member of the handles structure, where they were
cached by the
data_table_CellSelectionCallback.
You can see the effect of toggling the plot type in the two illustrations that
follow. The one on the left shows the Sunspots v. Year plots, and the one on
the right shows the FFT Periodograms Plots. The selection in both cases is
the years 1901–1950.
