Any good examples of the JFreechart extension?

[wigoe]

I use JFreechart quite a bit and wanted to see how ojalog incorporates it into its algorithms/code. Any examples?

ojAlgo in no way incorporates jfreechart.

The ojAlgo-jfreechart extension artifact contains some standardsed chart builders/factories. Some of which make use of ojAlgo data types (like time series).

The chart in the lower part of this screenshot

is produced using high level code like this:

    public static JFreeChartAdaptor makeHistoryAndForecast(final BLMarket market) {

        HistoryAndForecastBuilder retVal = new HistoryAndForecastBuilder();

        for (BLAssetClassCategory instrument : market.getAssetClassCategories()) {
            CalendarDateSeries<RandomNumber> series = instrument.getSeriesWithForecast();
            retVal.add(series);
        }

        retVal.legend(false);

        return retVal.build();
    }
