Constructor Detail

### IntervalMarker

    public IntervalMarker(double start,
                          double end)

  Constructs an interval marker.

  Parameters:
    `start` - the start of the interval.
    `end` - the end of the interval.

### IntervalMarker

    public IntervalMarker(double start,
                          double end,
                          java.awt.Paint paint)

  Creates a new interval marker with the specified range and fill paint. The outline paint and stroke default to `null`.

  Parameters:
    `start` - the lower bound of the interval.
    `end` - the upper bound of the interval.
    `paint` - the fill paint (`null` not permitted).
