Plotly subplots and graph objects error: Trace type 'scatter3d' is not compatible with subplot type 'xy' at grid position

Question

I get this error when I try to add_trace to a sunbplots. The plot is a graph objects object.

fig = make_subplots(rows = len(dfbh['client'].value_counts().index.tolist()), cols = 1)
scatbh = go.Scatter3d(x=dfbhtemp['x_local'], y=dfbhtemp['y_local'], z=dfbhtemp['z_local'], mode = 'markers', )
scatrun = go.Scatter3d(x=dfrunstemp['x_local'], y=dfrunstemp['y_local'], z=dfrunstemp['z_local'], mode = 'markers')
fig.add_trace(scatbh, row = 1, col = 1)
fig.add_trace(scatrun, row = 1, col = 1)
fig.show()

ValueError:  Trace type 'scatter3d' is not compatible with subplot type 'xy'
at grid position (2, 1)

These plots plot normaly when using subplots with no rows or columns.

I had the same error and the following worked for me: https://github.com/plotly/plotly.py/issues/3315#issuecomment-1164393438

You need to specify the chart type in the specs argument of the make_subplots function. Below is an example a 2x2 subplot figure.

fig = make_subplots(
    rows=2, 
    cols=2,
    start_cell="top-left", 
    specs=[
        [{"type": "scatter3d"}, {"type": "scatter3d"}], 
        [{"type": "scatter3d"}, {"type": "scatter3d"}]
    ]
)
