how to remove states from plotly Scattergeo trace?

I was reading through the Scattergeo documentation to remove Alaska and Hawaii from the 'usa' scoped without success. No functionality to access a specific subunit. Is there any workaround to perform this?

Solution

  • Ok, so this solved my issue. I had to superimpose a new trace. Take into account that the marker_line_color has to be set equal to your paper_bgcolor, once you got this, in order to avoid some aliasing between the Cholorpleth and the Scattergeo, set the marker_line_width to something bigger than the default value, e.g. 2.

    chorpleth = go.Choropleth(
        locationmode='USA-states',
        z=[0,0],
        locations=['AK','HI'],
        colorscale = [[0,'rgba(0, 0, 0, 0)'],[0,'rgba(0, 0, 0, 0)']],
        marker_line_color='#fafafa',
        marker_line_width=2,
        showscale = False,
    )

fig.add_trace(chorpleth, row=1, col=1)
