I find the stacked chart useful for separately displaying individual channels of time-aligned data on a common X Time axis. If the number of acquired channels is changed at run time, one would hope to correspondingly change the number of plots in the stacked chart. It currently is not possible to change the number of plots on a stacked chart at run time.

An option might be to use a Mixed Signal Graph instead but it does not seem possible to easily add or subtract plot areas at run time and have them occupy equal percentages of the plot area like the stacked chart's plots do. Additionally, the Mixed Signal Graph has the advantages of being able to use cursors and not having to know and define a chart history length.
