Hi Tom,
You can add the series to the chart yourself via code and set the Style property of the Marker based on the value of the points in the series. If the value of the point is less than 0, set the Style property of the Marker to Style = MarkerStyle.InvTriangle, otherwise, set it to Style = MarkerStyle.Triangle. Also, set the alignment to top or bottom accordingly for the Label property of the Marker.
