increment

Constructor Summary

UserDefinedScaleCalculator(double userDefinedMinimum, double userDefinedIncrement)
It would seem to make sense to pass in the min and the max, but we want to allow people to use custom implementations which will be created when the AxisChart constructor gets called and we will not have looped the data to find the min and max yet.

Method Summary

protected void

computeIncrement() Computes the axis increment WITHOUT taking into account the user specified rounding criteria and sets it to the super class increment variable.

Constructor Detail

UserDefinedScaleCalculator

public UserDefinedScaleCalculator(double userDefinedMinimum,
                                  double userDefinedIncrement)

It would seem to make sense to pass in the min and the max, but we want to allow people to use custom implementations which will be created when the AxisChart constructor gets called and we will not have looped the data to find the min and max yet. No sense in making people do that when we will do that already.

Parameters:

userDefinedMinimum -

userDefinedIncrement -

Method Detail

computeIncrement

protected void computeIncrement()

Computes the axis increment WITHOUT taking into account the user specified rounding criteria and sets it to the super class increment variable. You can extend this class and override this method to compute you own scale.
