Creates a new axis.

Parameters:

label - the axis label.

 public  void addSubLabel(Comparable category,
    String label) 
{
        this.sublabels.put(category, label);

Adds a sublabel for a category.

Returns a clone of this axis.

}

Overrides the default behaviour by adding the sublabel to the text block that is used for the category label.
