I have a TimeSeriesChartGenerator, to which I am adding several XYSeries. I
would for one of the series to not show by default and the following
snippet accomplishes this:

popChart.addSeries(weatherSeries, null).setPlotVisible(false);

However, the "Show" check box is still checked, which is inconsistent with
what's on the screen. Does anyone know a remedy for this?

Thanks,
Joey
