 public SurveyScaleExpression(int lowest,
    int highest) 
{
    this(lowest, highest, null, null, null);
}

Creates a new expression.

Parameters:

lowest - the lowest value on the response scale.

highest - the highest value on the response scale.

 public SurveyScaleExpression(int lowest,
    int highest,
    String lowerBoundsField,
    String upperBoundsField,

    this.rangeLowerBoundField = lowerBoundsField;
    this.rangeUpperBoundField = upperBoundsField;
    this.rangePaint = Color.lightGray;
}

Creates a new expression.

Parameters:

lowest - the lowest value on the response scale.

highest - the highest value on the response scale.

lowerBoundsField - the name of the field containing the lower bound of the highlighted range (null permitted).

upperBoundsField - the name of the field containing the upper bound of the highlighted range (null permitted).

shape - a shape that will be used to override the shape displayed for the first series (null permitted).

 public  void setOverrideShape(Shape shape)

}

Sets the override shape. The SurveyScale is created with a set of default shapes, this method allows you to replace the *first* shape if you need to (leave it as null otherwise).

 public  void setOverrideShapeFilled(boolean b) 
{
    this.overrideShapeFilled = b;
}

Sets a flag that controls whether the override shape is filled or not.

 public  void setRangeLowerBoundField(String field) 
{
    this.rangeLowerBoundField = field;
}

Sets the name of the field containing the lower bound of the range that is to be highlighted on the scale. Set this to null if you have no range to highlight.

 public  void setRangePaint(Paint rangePaint) 
{
    if (rangePaint == null)
    {
      throw new NullPointerException();
    }
    this.rangePaint = rangePaint;
}

 public  void setRangeUpperBoundField(String field) 
{
    this.rangeUpperBoundField = field;
}

Sets the name of the field containing the upper bound of the range that is to be highlighted on the scale. Set this to null if you have no range to highlight.
