The auto scale Y function resets the current view port along the y-axis and re-scales all objects enclosed
in a way, that the maximum y-axis range of all objects enclosed is visible again. All other axes remain unchanged. Whenever the user wants to see
the full data range along the y-axis of all objects, e.g. after he has zoomed into a particular data objects area to see details, he might apply
this function.
The auto scale Y function is applied to all available data objects in the current active data view. So the view port is re-scaled to show the
complete y-axis of all data objects. If you just like to re-scale the view port to fit the current active object, please use the auto
scale Y active function.
This function is used with 2D data
objects and 3D data objects.
