Hi, Just starting with Dash and loving it… until I tried to have a filter to update a map (MapBox). The first callback generating the map works well, map is displayed. When I select on filter, the callback seems to run (I get the updated print(len(dff)), but the Map doesn’t get updated. On the other side my table is updated correctly by the filter Did my research and suspect a version issue but I tried to downgrade and it didn’t change ( [https://github.com/plotly/dash/issues/223](https://github.com/plotly/dash/issues/223) ) I’m dying for help here!!! 😉 Flo Here is my code and versions: **1) Requirements** ```auto dash==1.10.0 dash-core-components==1.9.0 dash-html-components==1.0.3 dash-renderer==1.3.0 dash-table==4.6.2 dash-table-experiments==0.6.0 ``` **2) Map Function** ```auto def gen_map(df): return { "data": [{ "type": "scattermapbox", "lat": list(df['Latitude']), "lon": list(df['Longitude']), "hoverinfo": "text", "hovertext": [["Name: {}
Type: {}
Provider: {}".format(i,j,k)] for i,j,k in zip(df['Nom'], df['Livraison'],df['Commune'])], "mode": "markers", "name": list(df['Nom']), "marker": { "size": 6, "opacity": 0.7 } }], "layout": layout_map } ``` **3) Map Layout:** ```auto layout_map = dict( autosize=True, height=500, font=dict(color="#191A1A"), titlefont=dict(color="#191A1A", size='14'), margin=dict( l=35, r=35, b=35, t=45 ), hovermode="closest", plot_bgcolor='#fffcfc', paper_bgcolor='#fffcfc', legend=dict(font=dict(size=10), orientation='h'), #title='WiFi Hotspots in NYC', mapbox=dict( accesstoken=MAPBOX_API_TOKEN, #style="light", center=dict( lat=df['Latitude'].mean(), lon=df['Longitude'].mean() ), zoom=10, ) ) ``` **4) Dash Component** ```auto html.Div( [ dcc.Graph(id='map-graph', animate=True, style={'margin-top': '20'}) ] #, className="six columns" ), ``` **5) Map Callback** ```auto def map_selection(city , delivery): if type(city) is list and city and type(delivery) and delivery: dff = df[(df['Commune'].isin(city)) & (df['Livraison'].isin(delivery))] elif type(city) is list and city: dff = dff = df[(df['Commune'].isin(city))] elif type(delivery) is list and delivery: dff = dff = df[(df['Livraison'].isin(delivery))] else: dff = df print(len(dff)) print('generate map') return gen_map(dff) ``` ---

Hi @flohaha regarding possible version conflicts, you can try to uninstall all the above packages and install only `dash` again, which will install compatible versions of all other packages (`dcc`, `html`, `dash-table` etc.) Incompatible versions of `dash` and `dcc` have been a frequent source of empty plots like yours in the past so let’s keep fingers crossed that this is the issue. ---

Not sure if this was ever resolved but I am experiencing the same issue with the latest versions of plotly and dash! ---
