A Overlay is a collection of HoloViews objects that are related in some way, to be displayed simultaneously, overlaid in the same space. Like
Layout and unlike other containers such as
Overlay is not dictionary like: it holds potentially heterogeneous types without any dimensioned keys.
Overlay cannot contain any other container type other than
NdOverlay but can contain any HoloViews elements. See Building Composite Objects for more details on how to compose containers. It is best to learn about
Layout together as they are very closely related objects that share many core concepts.
Overlay is a heterogeneous collection#
You can build a
Overlay between any two HoloViews objects (which can have different types) using the
xvals = [0.1* i for i in range(100)] curve = hv.Curve((xvals, [np.sin(x) for x in xvals])) scatter = hv.Scatter((xvals[::5], np.linspace(0,1,20))) curve * scatter
In this example, we have a
Overlay composed of a
Curve element and a
