Method Detail

createXYSeriesCollection

public static org.jfree.data.xy.XYSeriesCollection createXYSeriesCollection(ValueSource valueSource,
                                                                            PlotInstance plotInstance,
                                                                            double autoWidthFraction,
                                                                            boolean allowDuplicates,
                                                                            boolean sortByDomain)

Parameters:

valueSource -

plotInstance -

autoWidthFraction - If this value is greater than 0, an auto width for the intervals is calculated such that the intervals nearest to each other touch. This value is then multiplied with the value of autoWidthFtraction. If unset, the intervals have width 0.

allowDuplicates -

sortByDomain - if true, the data is sorted by domain values (useful for bar and area charts)

Returns:

Throws:

ChartPlottimeException

These are collected in the list for the appropriate datapoint in the dataset.
