auto_xy_EnvelopeΒΆ

auto_xy_Envelope creates an upper or lower envelope (hull, boundary).

hDataNew = auto_xy_Envelope(hData_Layer, rsWidth, nType)

Return Value

hDataNew is the handle of the new dataset.

Parameters

hData_Layer

hData_Layer is a vector with two elements. The first element is a handle of a 2D dataset and the second element is a handle of a layer (diagram) to which the new dataset should be added.

rsWidth

rsWidth specifies the width of the window in percent (%). Valid values must be in the range 0.1 % to 100 %. With smaller windows the hull curve will follow closer to the data of the dataset hData (Default value is 5 %).

nType

nType specifies the hull type (Default value is 1):

Value Meaning
1 upper hull
2 lower hull

Comment

The data must have increasing x-coordinates.
