sp4:
public enum MarkerShape { none, filledCircle, filledSquare, openCircle, openSquare, filledDiamond, openDiamond, asterisk, hashTag, cross, eks, verticalBar, triUp, triDown, filledTriangleUp, filledTriangleDown, openTriangleUp, openTriangleDown, }

sp5:
public enum MarkerShape { None, FilledCircle, OpenCircle, FilledSquare, OpenSquare }
sp4:
AddArrow
AddPoint
