java.lang.Object de.lmu.ifi.dbs.elki.visualization.scales.LinearScale
public class LinearScale
Class to handle a linear scale for an axis. The computed scales are rounded to be on decimal borders, choosing an appropriate resolution to have between 4 and 31 major tics (3 to 30 intervals). Future versions might use major/minor tics to get even nicer values.
