Chromium based browsers showed an error message in the developer tools:

Error: <rect> attribute width: A negative value is not valid.

This error was provoked by a broken windowing function in the python implementation and is now fixed.

Furthermore the calculation of the windowing function was adapted: Before the first and last Bar was not a full sized window based on the current time. Now all time windows have the same duration.
