Constructor Detail

ChartModelImpl

public ChartModelImpl(int bufferPagesCount,
                      @NotNull
                      java.util.concurrent.Executor workersPool)

Parameters:

bufferPagesCount - number of chart data pages to keep in memory. E.g. if 1 is returned, then the chart would keep one page before the current interval and one page after the current interval

workersPool - thread pool to use for data loading
