Axis labels are not shown for all subplots when usin... | plotly/plotly.py

Ninguém assumiu esta issue ainda.

Problem summary

Whenever I have the following combination:

plotly express
facet plots
labels used for axis are strings

The first subplot shows the axis labels properly, but all following subplots don't show labels at all:
Plot showing the issue
If the axis labels are numbers, there is no problem.

From a comment of the initial issue I opened I now know that fig.update_traces(bingroup='x2', row=1, col=2) can work around the issue, but that's not a permanent solution.

Reproducible example

I originally created these plots in Python (plotly 5.18.0) and then used the .to_json(pretty=True) method to obtain the Javascript for the codepens.

Manually building up the figure using graph_objects and make_subplots I get the following working visualization: https://codepen.io/sl1970/pen/BaMvNbp
If I use the convenient plotly.express library and the facet argument I get this broken visualization (no axis labels on the right plot): https://codepen.io/sl1970/pen/jOdXPoa

Original Python code

If necessary, this is the original Python code I used

import pandas as pd
import plotly.express as px
from plotly.subplots import make_subplots
import plotly.graph_objects as go

df = pd.DataFrame(
    {
        "age": { "0": "Adult", "1": "Adult", "2": "Adult", "3": "Adult", "4": "Adult", "5": "Kid", "6": "Kid", "7": "Kid", "8": "Kid", "9": "Kid", },
        "favourite_food": { "0": "Pizza", "1": "Noodles", "2": "Pizza", "3": "Pizza", "4": "Pizza", "5": "Burger", "6": "Pancake", "7": "Noodles", "8": "Pizza", "9": "Pancake", },
        "favourite_drink": { "0": "Beer", "1": "Tea", "2": "Beer", "3": "Wine", "4": "Coffee", "5": "Coffee", "6": "Water", "7": "Beer", "8": "Tea", "9": "Wine", },
        "max_running_speed": { "0": 4.7362803248, "1": 16.7084927714, "2": 8.1135697835, "3": 1.0704264989, "4": 4.6330187561, "5": 6.331593807, "6": 16.5221040135, "7": 3.2256763127, "8": 4.3084468631, "9": 6.3677742299, },
        "number_of_bicycles": { "0": 4, "1": 2, "2": 1, "3": 3, "4": 4, "5": 3, "6": 3, "7": 3, "8": 4, "9": 2, },
    }
)
df.set_index("age", inplace=True)


working = make_subplots(rows=1, cols=2, subplot_titles=["Food", "Drink"])

working.add_trace( go.Histogram( histfunc="count", histnorm="percent", x=df.loc["Adult"].favourite_food, name="Adult", legendgroup="Adult", ), row=1, col=1, )
working.add_trace( go.Histogram( histfunc="count", histnorm="percent", x=df.loc["Kid"].favourite_food, name="Kid", legendgroup="Kid" ), row=1, col=1, )
working.add_trace( go.Histogram( histfunc="count", histnorm="percent", x=df.loc["Adult"].favourite_drink, name="Adult", legendgroup="Adult", ), row=1, col=2, )
working.add_trace( go.Histogram( histfunc="count", histnorm="percent", x=df.loc["Kid"].favourite_drink, name="Kid", legendgroup="Kid" ), row=1, col=2, )
working.show()

broken = px.histogram(
    df,
    x=["favourite_food", "favourite_drink"],
    facet_col="variable",
    color=df.index,
    barmode="group",
    histnorm="percent",
    text_auto=".2r",
).update_xaxes(matches=None, showticklabels=True).update_yaxes(matches=None, showticklabels=True)
broken.show()

Comece com o tratamento de histogramas e facets do plotly.express descrito no exemplo reproduzível em Python e, em seguida, compare a figura gerada com o exemplo funcional de make_subplots e os CodePens vinculados. Considera-se concluído quando os rótulos de eixo categóricos do tipo string forem renderizados em todos os facets sem exigir um workaround de bingroup, com um teste de regressão cobrindo esse caso.
