Examples of com.positive.charts.data.time.DateRange

com.positive.charts.data.time.DateRange
A range specified in terms of two java.util.Date objects. Instances of this class are immutable.

    final double length = (this.timeline.toTimelineValue((long) this
        .getRange().getUpperBound()) - this.timeline
        .toTimelineValue((long) this.getRange().getLowerBound()));
