Sorry, i think regenerate a chart have some performance problem.
I have tried to generate charts continually,and use 'chartPanel.setChart()'
to put them into a Chart Panel.
The UI keeped ruuning for only 2 hours,and then dumped.200 M RAM had been occupied.

What about removing the series you want to hide, save it in a TimeSeries variable (or a Vector if you have more than one) and then just adding it again when you want it to be shown? then, you'll only have to repaint the chart.

Aha,I have the same idea with you.But the way still have a problem.
I can remove a series easy,but it is some difficult in readd it into the chart with correct position.
