auto_xy_Add

auto_xy_Add creates a new dataset from the sum of the y-coordinates of 2D datasets.

hDataNew = auto_xy_Add(hData, hvData)

hDataNew = auto_xy_Add(hData_Layer, hvData)

Return Value

hDataNew is the handle of the new dataset.

Parameters

hData

hData is the handle of a 2D dataset. The new dataset, hDataNew, will be added to the layer (diagram) where the dataset hData is located.

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.

hvData

hvData is a vector of handles of 2D Datasets.

Comment

The x-coordinates of all given datasets must be strictly increasing. They do not have to be identical.

The new dataset is calculated as following:

• The x-range is calculated where all datasets overlap.
• Within the new x-range, a new x-coordinate vector (xs) is calculated which contains the x-coordinates of all given datasets.
• For each dataset, y-coordinates for the new x-vector xs will be calculated by linear interpolation.
• The interpolated y-coordinates are added (yadd).
• A new dataset will be created (xs, yadd).
