Examples of com.positive.charts.axis.ticks.TickUnit

com.positive.charts.axis.ticks.TickUnit
Base class representing a tick unit. This determines the spacing of the tick marks on an axis.
This class (and any subclasses) should be immutable, the reason being that ORDERED collections of tick units are maintained and if one instance can be changed, it may destroy the order of the collection that it belongs to. In addition, if the implementations are immutable, they can belong to multiple collections. @see ValueAxis

    double tickLabelWidth = this.estimateMaximumTickLabelWidth(g2, this
        .getTickUnit());


    // start with the current tick unit...
    final TickUnitSource tickUnits = this.getStandardTickUnits();
    final TickUnit unit1 = tickUnits.getCeilingTickUnit(this.getTickUnit());
    final double unit1Width = this.lengthToJava2D(unit1.getSize(),
        dataArea, edge);


    // then extrapolate...
    final double guess = (tickLabelWidth / unit1Width) * unit1.getSize();


    NumberTickUnit unit2 = (NumberTickUnit) tickUnits
        .getCeilingTickUnit(guess);
