Plotly Express multiple plots overlay

[shakasom]

If I want to have two plotly express figures plotted on the same axis. What should I do.

I tried this:

fig = px.scatter_mapbox(points, lat="ycoord", lon="xcoord")
fig.add_trace(px.scatter_mapbox(stations, lat="ycoord", lon="xcoord",))
fig

But it is not working. I have two points dataset and want to see both on the same map.

Hi @shakasom, welcome to the forum! plotly express functions return a figure object (with data and layout). So, to add a trace to your existing figure created by plotly express, you can either

• use a plotly.graph_objects.Scattermapbox object which defines the trace (https://plot.ly/python-api-reference/generated/plotly.graph_objects.Scattermapbox.html) in fig.add_trace
• or select the data part only from the second figure created by px, lilke

fig.add_trace(px.scatter_mapbox(stations, lat="ycoord", lon="xcoord",).data[0])

[shakasom]

fig.add_trace(px.scatter_mapbox(stations, lat=“ycoord”, lon=“xcoord”,).data[0])

Thanks @Emmanuelle. I understood and successfully used the second option. You add the trace with fig.data and by the way I stumbled upon that colors and markers can be changed using fig.data. That was cool.
