   de.progra.charting.model.DefaultChartDataModelConstraints

DefaultChartDataModelConstraints
public class DefaultChartDataModelConstraints implements ChartDataModelConstraints(Code)
Implementing the ChartDataModelConstraints this class provides the default implementation for the data model constraints. Alternative implementations could return the sum of all column values to implement stacked bar charts e.g.
author:
   smueller


Field Summary
protected  booleanallowManualColScale
     A flag which determines if column values should be manually scalable.
protected  intaxis
     The axis to compute the constraints.
protected  AbstractChartDataModelmodel
     The model for which to calculate the constraints.

Constructor Summary
public  DefaultChartDataModelConstraints(AbstractChartDataModel model, int axis)
    
public  DefaultChartDataModelConstraints(AbstractChartDataModel model, int axis, boolean allowManualColScale)
    

Method Summary
public  doublegetMaximumColumnValue()
     Returns the maximum column value.
public  NumbergetMaximumValue()
     Returns the maximum value of all datasets.
public  doublegetMinimumColumnValue()
     Returns the minimum column value.
public  NumbergetMinimumValue()
     Returns the minimum value of all datasets.

Field Detail
allowManualColScale
protected boolean allowManualColScale(Code)
A flag which determines if column values should be manually scalable.



axis
protected int axis(Code)
The axis to compute the constraints.



model
protected AbstractChartDataModel model(Code)
The model for which to calculate the constraints.




Constructor Detail
DefaultChartDataModelConstraints
public DefaultChartDataModelConstraints(AbstractChartDataModel model, int axis)(Code)
Creates a new instance of DefaultChartDataModelConstraints



DefaultChartDataModelConstraints
public DefaultChartDataModelConstraints(AbstractChartDataModel model, int axis, boolean allowManualColScale)(Code)
Creates a new instance of DefaultChartDataModelConstraints
Parameters:
  model - the AbstractDataModel for which constraints will be computed
Parameters:
  axis - the y-axis which will be considered
Parameters:
  allowManualScale - a flag which triggers if column values should be allowed to be scaled manually (default is yes)




Method Detail
getMaximumColumnValue
public double getMaximumColumnValue()(Code)
Returns the maximum column value.
throws:
  ArrayIndexOutOfBoundsException - if the model is empty



getMaximumValue
public Number getMaximumValue()(Code)
Returns the maximum value of all datasets.



getMinimumColumnValue
public double getMinimumColumnValue()(Code)
Returns the minimum column value.
throws:
  ArrayIndexOutOfBoundsException - if the Model is empty



getMinimumValue
public Number getMinimumValue()(Code)
Returns the minimum value of all datasets.
