I'm trying to create a time slider which varies by day, however, 1) all MultiPolygons are initially displayed at once for the first time stamp and 2) if I use the slider from the start to the end of the slider, all previous time steps are overlaid by the final time step.

Note: All MultiPolygons are not consistent in terms of shape/size. I think this is related to the issue.

Here's a screen capture of the issue: There shouldn't be any overlapping lines on the map for the initial time stamp.

The final slide looks good:

However, once I scroll through all slides once, all data is overlaid by the final time stamp:

Here's the important part of the script:

---create a style dictionary

styledata = {} for i in range(allgpd.shape[0]): subset = allgpd.iloc[i] idxname = pd.Index([subset.times], dtype="U10") df = pd.DataFrame({"color": allgpd['color'][i],"opacity": 1,},index=idxname,) styledata[i] = df

---reformat

styledict = {str(idx): data.to_dict(orient="index") for idx, data in styledata.items()}

---create the folium slider

m = folium.Map(location=[qlat, qlon], zoom_start=6) g = TimeSliderChoropleth( allgpd.to_json(), styledict=styledict, control=True, overlay=True, show=False).add_to(m) m

I also attached my script in its entirety to this thread, as well (script.txt).

Environment details (Jupyter Notebook): System: sys.version_info(major=3, minor=9, micro=12, releaselevel='final', serial=0) Folium: 0.14.0 Branca: 0.6.0

I attached the data to this thread (data.zip).
