Plotly Express cannot process wide-form data with columns of different type. #4266
Description
Hi! When running the following code:
df = pd.DataFrame({'numeric': [1, 2], 'string': ['A', 'B']})
fig = px.scatter(df, x=df.columns, facet_col='variable')
fig.show()
We get the following error:
ValueError: Plotly Express cannot process wide-form data with columns of different type.
Expected output is:
We understand the need for prevention of data type mixing for other type of plots, but for scatter or line plots use cases like expected output can be very common. Commenting the following code:
elif dtype != v_dtype:
raise ValueError(
"Plotly Express cannot process wide-form data with columns of different type."
)
In plotly/express/_core.py gives us expected output.
