Notification.SET,
					TypePackage.LINE_SERIES__MARKER,
					newMarker,
					newMarker ) );
	}
	/**
	 * <!-- begin-user-doc --> <!-- end-user-doc -->
	 * @generated
	 */
	public LineAttributes getLineAttributes( )
	{
		return lineAttributes;
	}
	/**
	 * <!-- begin-user-doc --> <!-- end-user-doc -->
	 * @generated
	 */
	public NotificationChain basicSetLineAttributes(
			LineAttributes newLineAttributes, NotificationChain msgs )
	{
		LineAttributes oldLineAttributes = lineAttributes;
		lineAttributes = newLineAttributes;
		if ( eNotificationRequired( ) )
		{
			ENotificationImpl notification = new ENotificationImpl( this,
					Notification.SET,
					TypePackage.LINE_SERIES__LINE_ATTRIBUTES,
					oldLineAttributes,
					newLineAttributes );
			if ( msgs == null )
