Hi,
I am updating an Java application, already using JFreeChart, to handle time series of frequency histograms. That is, at each sampling time I get the frequency of different occurances sorted in a fixed number of bins. Sampling is done at varying time intervals. So to me this is a time series of histograms as you can also image a time series of wind vectors or other multi-dimensional data. My guess is that I can use a TimeSeriesCollection with a time series for each bin?
Still I loose a bit of "information" as I would like to see it as a single time series where each data point is a histogram. Can TimeSeries or maybe rather TimeSeriesDataItem be extended to not only contain scalar data but contain more arbitary, multi-valued, data types?
