If the bubble is an aggregate based on an ID column, all of the rows for that ID are highlighted. Otherwise, the one row represented by that bubble is highlighted.
If you specify an ID and a Time variable, selecting a bubble highlights all of the rows for that ID, across all of the Time levels.
If you have not specified a Time variable, selecting one row from the data table highlights the corresponding bubble in the plot.
If you have specified a Time variable, selecting one row from the data table highlights the corresponding bubble for only that time period in the dynamic bubble plot.
