Class DoubleAxis

java.lang.Object
  jas.plot.AxisType
      jas.plot.DoubleAxis

All Implemented Interfaces:

CoordinateTransformation, DoubleCoordinateTransformation, Transformation, Externalizable, Serializable

public final class DoubleAxis
extends AxisType
implements DoubleCoordinateTransformation

Implements a simple numeric axis, with either linear or logarithmic scale. Users may set a flag that determines whether the axis may round to close values for simplicity of labels or whether the axis should keep to the given range. If, for example, the minimum is set to 4.3 and the maximum is set to 95.9, this class may be configured to round the extrema so that the labels are 0, 10, 20, ..., 100. Use setUseSuggestedRange(boolean) to set whether a pretty range is automatically used.
