XYSeries Size Limit

[David Mellar]

Is there any quick method to limit the XYSeries data to the last x number?

[Dave Gilbert]

Not yet. There is a setMaximumItemCount(...) method in the BasicTimeSeries class, and I need to port something similar across to the XYSeries class. If you are in a hurry, then take a look at the way it is done in BasicTimeSeries...

Thanks. I tried the following:

int maxChartSize = 100;
if (seriesAverage.getItemCount() >= maxChartSize) {
seriesAverage.delete(0,0);
}

And it works, but I occationally get the following exception:
I tried hunting down the problem, but no luck. Any advice?
