Functions in depthseries widgets does not work

We need some analysis for the functions Sin, Cos and random which can be added as data sources in widgets.

Those data are supposed to be timeseries (maybe) and if so it does not makes sense to be available in depthseries widgets.

If we need it in depthseries then it should work as expected (what is expected in this case) which is not the case as of now. It keeps waiting for data and nothing is rendered in the widgets.
