Possible bug in px.scatter_3d, SIZE parameter

📊 Plotly Python
1

I have created a scatter3d chart with plotly express to show the difference in values, for a conversion dataset. The scatter3d works well as follows

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]
})

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

with the following result:

newplot (37)
newplot (37)1476×525 8.15 KB

notice three big bubbles on the top layer, and one big bubble on the bottom layer.

now, when I update the color to be the same as the z dimension

color="type"

the SIZE parameter changes. notice now two big bubbles on top, and two big bubbles on the bottom. the with hover_data turned on we can confirm that the size of the bubble is no longer reflected by the right column.

this seems like a bug. has anyone experienced this before? If new I will open a new issue on github.
