Dynamically updating charting based on changes to dataset

Hi All,

First off, thanks to David Gillbert and to all that have contributed to making such a fine charting component.

I have been experimenting a bit with the chart in order to plot stock market data between the 1 minute and daily range. I'm using DateAxis with the SegmentedTimeline refinement to filter out the weekends and my own implementation of OHLCDataset that uses an ArrayList as opposed to an array to allow it to grow in size dynamically with minimal overhead.

My problem is that I'm not exactly sure how to tell the chart to "refresh" itself against the underlying dataset when I have made changes to values (the current bar) or when I insert new bars. Is there some function I'm supposed to call to tell the chart to refresh the data?

Thanks in advance.

My apologies, I just noticed while looking at another class that there is a firedatasetChanged() method that I somehow overlooked.
