Parcats not support displaying the category name

Summary of the issue: You wanted to display the category name on hover in a go.Parcats plot using Plotly for Python. We tried using the hoverinfo and hovertemplate parameters to achieve this, but these parameters do not support displaying the category name. Currently, it seems that it is not possible to directly display the category name on hover in a go.Parcats plot using Plotly for Python.

Report: Dear Plotly Developers,

I recently encountered an issue while creating a go.Parcats plot using Plotly for Python. I wanted to display the category name on hover, but I found that this functionality does not seem to be possible.

I tried using the hoverinfo and hovertemplate parameters to achieve this, but these parameters do not support displaying the category name. Upon further investigation, I found that it is currently not possible to directly display the category name on hover in a go.Parcats plot using Plotly for Python.

I believe this is an important feature that would help users better understand the data in the plot. Therefore, I strongly suggest that you consider adjusting this issue to support displaying the category name on hover in future versions.

Thank you for your attention to this matter and I look forward to your response.

import plotly.graph_objs as go
from plotly.offline import iplot

# Create a trace for the parcats plot
parcats = go.Parcats(
    dimensions=[
        {'label': 'Category A',
         'values': ['A1', 'A2', 'A3']},
        {'label': 'Category B',
         'values': ['B1', 'B2', 'B3']}
    ],
    hovertemplate='%{dimension.label}'
)

# Create the layout
layout = go.Layout(
    title='Parcats Plot with Hover Text'
)

# Create the figure
fig = go.Figure(data=[parcats], layout=layout)

# Show the plot
iplot(fig)

まず、提供されている Python go.Parcats の例を実行し、現在のホバー出力を要求されたカテゴリ名と比較します。次に、Parcats が hovertemplate と dimension labels をどのように処理しているかを追跡し、既存のホバー内容を壊さずにカテゴリ名がホバー時に表示されることを確認します。
