AxisRange

public AxisRange()

AxisRange

public AxisRange(double lowerBound,
                 double upperBound,
                 double axisLength,
                 double scale,
                 double tickUnit)

Method Detail

toString

public java.lang.String toString()

Parameters:

range - range to be added

substract

public AxisRange substract(AxisRange range)

Substracts the specified data range from this range. TODO: check algorithm definiton

Parameters:

range - range to be subtracted

Returns:

this axis with reduced limits

hashCode

public int hashCode()

Overrides:

hashCode in class de.gsi.dataset.spi.DataRange

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class de.gsi.dataset.spi.DataRange
