I have the code ...
plugins.TimestampedGeoJson ( { 'type': 'FeatureCollection', 'features': features }, period = 'PT1M', transition_time = 100, loop = False, auto_play = False, duration = 'PT1M' ).add_to(m)
and I'm getting the error message ... TypeError: init() got an unexpected keyword argument 'duration'
The same happens with the parameter time_slider_drag_update. The map and time animation works fine without these parameters but I'm getting a stack of markers on top of each other because I'm not removing the markers after the timestamp has finished if that makes sense. I want the map to refresh not build.
