px.scatter_3d, use case where color param affects size output

[ua-chjb]

I have created a scatter3d chart with plotly express. The scatter3d works fine with column "count" as size (fig 1). There are three big bubbles on the top layer and one on the bottom layer.

fig1

I next add the color parameter to be a column "type" in the frame. The resulting plot appears to have incorrectly swapped out "count" for "type" in the size parameter, so now the actual size param is ignored and it maps color to size. (fig 2).

fig2

import pandas as pd
import plotly.express as px

df = pd.DataFrame({
    "campaign": ["funny", "funny", "funny", "funny", "patriotic", "patriotic", "patriotic", "patriotic"],
    "product": ["classic", "classic", "diet", "diet", "classic", "classic", "diet", "diet"],
    "type": ["click", "land", "click", "land", "click", "land", "click", "land"],
    "count": [397, 108, 108, 411, 99, 410, 144, 323]
})

fig1 = px.scatter_3d(df, x="campaign", y="product", z="type", hover_data="count").update_traces({"marker": {"size": [j/10 for j in df["count"]]}})

fig2 = px.scatter_3d(df, x="campaign", y="product", z="type", hover_data="count", color="type").update_traces({"marker": {"size": [j/10 for j in df["count"]]}})

Thanks for the report @ua-chjb - can you please let us know which versions of Python and Plotly you are using, on which OS and with which browser? Thanks - @gvwilson
