It's amazing.\r\nI've been trying to make a subplot of ScatterMapbox (e.g.: Two maps, one below the other) without success. I'm trying this in a jupyter notebook:\r\n- linux debian buster\r\n- Firefox 68.0.1\r\n- python 3.6.9\r\n- jupyter 1.0.0\r\n- plotly 4.1.0\r\n\r\nThe code I use is:\r\n```python\r\nfig = make_subplots(\r\n    rows=2, cols=1,\r\n    specs=[[{'type': 'mapbox'}],[{'type': 'mapbox'}]],\r\n    subplot_titles=('Montreal 1','Montreal 2'),\r\n)\r\n\r\nfig.add_trace(go.Scattermapbox(\r\n        lat=['45.5017'],\r\n        lon=['-73.5673'],\r\n        mode='markers',\r\n        marker=go.scattermapbox.Marker(\r\n            size=14\r\n        ),\r\n        text=['Montreal'],\r\n    ), row=1, col=1\r\n)\r\n\r\n\r\nfig.add_trace(go.Scattermapbox(\r\n        lat=['45.6017'],\r\n        lon=['-73.7673'],\r\n        mode='markers',\r\n        marker=go.scattermapbox.Marker(\r\n            size=14\r\n        ),\r\n        text=['Montreal 2'],\r\n    ), row=2, col=1\r\n             )\r\n\r\nfig.update_layout(\r\n    hovermode='closest',\r\n    mapbox=go.layout.Mapbox(\r\n        accesstoken=mapbox_access_token,\r\n        bearing=0,\r\n        center=go.layout.mapbox.Center(\r\n            lat=45,\r\n            lon=-73\r\n        ),\r\n        pitch=0,\r\n        zoom=5\r\n    )\r\n)\r\n\r\nfig.show()\r\n```\r\nThis results in an empty map:\r\n![Screenshot from 2019-08-19 20-04-14](https://user-images.githubusercontent.com/7479071/63288261-8c009780-c2bc-11e9-9e1e-8bf9048decf6.png)\r\nIn my browser console I have:\r\n```\r\nError: No valid mapbox style found, please set `mapbox.style` to one of:\r\nopen-street-map, white-bg, carto-positron, carto-darkmatter, stamen-terrain, stamen-toner, stamen-watercolor\r\nor register a Mapbox access token to use a Mapbox-served style.\r\n```\r\nPassing a `mapbox_style` to the layout does not seem to solve the issue.\r\n\r\nNote that running the simple montreal example from the doc works properly, even adding a single map to the subplot works too:\r\n```python\r\nfig = make_subplots(\r\n    rows=2, cols=1,\r\n    specs=[[{\"type\": \"mapbox\"}],[{\"type\": \"mapbox\"}]],\r\n    subplot_titles=(\"Montreal 1\",\"Montreal 2\"),\r\n)\r\n\r\nfig.add_trace(go.Scattermapbox(\r\n        lat=['45.5017'],\r\n        lon=['-73.5673'],\r\n        mode='markers',\r\n        marker=go.scattermapbox.Marker(\r\n            size=14\r\n        ),\r\n        text=['Montreal'],\r\n    ), row=1, col=1\r\n)\r\n\r\nfig.update_layout(\r\n    hovermode='closest',\r\n    mapbox=go.layout.Mapbox(\r\n        accesstoken=mapbox_access_token,\r\n        bearing=0,\r\n        center=go.layout.mapbox.Center(\r\n            lat=45,\r\n            lon=-73\r\n        ),\r\n        pitch=0,\r\n        zoom=5\r\n    )\r\n)\r\n\r\nfig.show()\r\n```\r\nI've tried passing multiple `Scattermapbox` to a figure's data but this results in two mapbox layers in the same map. At this point I'm starting to think that subplots are not supported with scattermapbox but as could not find anything regarding this in the docs,  I'm probably missing something.\r\n","author":{"url":"https://github.com/Timost","@type":"Person","name":"Timost"},"datePublished":"2019-08-19T18:13:14.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":13},"url":"https://github.com/1728/plotly.py/issues/1728"}
