                                              double xLow,
                                              double xHigh)

  Finds the lower index of the range of live items in the specified data series.

  Parameters:
    `dataset` - the dataset (`null` not permitted).
    `series` - the series index.
    `xLow` - the lowest x-value in the live range.
