another question i just want to combine
another question , i just want to combine cross filter with map (leafmap) however I couldn't make it work:
filter, _set_filter = solara.use_cross_filter(id(df))
solara.CrossFilterSelect(df, "class") solara.CrossFilterSelect(df, "name") solara.CrossFilterSlider(df, "Time", mode=">=")
dff = df.loc[filter] if filter is not None else df with solara.Columns([2, 2]): class Map(leafmap.Map): def init(self, kwargs): super().init(kwargs)
self.add_points_from_xy( dff, x="lon", y="lat", spin=True, add_legend=True, )
solara.CrossFilterDataFrame(dff) solara.FigurePlotly(px.histogram(dff, "Time")) how to solve and make interactively between filter, dataframe and map thanks
solara.CrossFilterSelect(df, "class") solara.CrossFilterSelect(df, "name") solara.CrossFilterSlider(df, "Time", mode=">=")
dff = df.loc[filter] if filter is not None else df with solara.Columns([2, 2]): class Map(leafmap.Map): def init(self, kwargs): super().init(kwargs)

what do you mean by "does not work" what behaviour do you expect that is not happening?

Hi @MaartenBreddels thanks for your reply, when I select based on filter specify all dataframe and plot was updated as the filter applied to them however nothing plot in the map

my example dataframe like this (just a dummy data):
df=pd.DataFrame(data={'class': [1, 2,3,25], 'name':['A1','A2','A3','A4'],'Time': [10, 20,30,40],'lat':[40.741895,40.73098527339601,40.66905379201422,-0.22470045920182688],'lon':[-73.989308,-74.12560713330078,-74.1163374189453,114.96660935839847]},dtype=np.int8)
zoom = solara.reactive(zoom_default)
center = solara.reactive(center_default)
marker_location = solara.reactive(center_default)
#map_name = solara.reactive(list(maps)[0])
