XYIsPolygonClosed

XYIsPolygonClosed determines whether the polygon is closed.

bClosed = XYIsPolygonClosed(hData)

Return Value

If bClosed is TRUE (1), the first data point will be joined to the last point and the enclosed area will be color filled. If FALSE (0), the area between the curve and a ground line parallel to the x-axis will be color filled. The height of the ground line can be set with the function XYSetDropValue.
