MCA --> show_rows and label visualization

[SodaMaremLo]

Is there an equivalent of PCA show_rows=False when plotting MCA?
And how can I visualize the labels in a static way?

I would like to save an image without row variables, and with all the column labels visible

Hey there @SodaMaremLo. I just implemented this as part of Prince 0.13.0. Here is an example:

import prince

dataset = prince.datasets.load_french_elections()
ca = prince.CA(n_components=3)
ca.fit(dataset)
ca.plot(
    dataset, 
    show_row_markers=True,
    show_row_labels=False,
    show_column_labels=True,
    show_column_markers=False
)

I hope this works for you!

Thank you a lot, it worked perfectly!!

Hello @MaxHalford, great work with your library!. I am having problems executing the before-mentioned code. I am having the following error:
`/Users/anaconda3/lib/python3.11/site-packages/altair/utils/core.py:827: UserWarning: Unrecognized encoding channel 'show_row_markers'

/Users/anaconda3/lib/python3.11/site-packages/altair/utils/core.py:827: UserWarning: Unrecognized encoding channel 'show_row_labels'

/Users/anaconda3/lib/python3.11/site-packages/altair/utils/core.py:827: UserWarning: Unrecognized encoding channel 'show_column_labels'

/Users/anaconda3/lib/python3.11/site-packages/altair/utils/core.py:827: UserWarning: Unrecognized encoding channel 'show_column_markers'
`

And after those warnings I got the following error:SchemaValidationError: Encoding has no parameter named 'show_row_markers' . It happens with every single option that appears on the warnings. I am using VS Code as the IDE on a Mac OS with python version 3.11. Thanks!

Nevermind, seems there is an issue with Python version 3.11.5; I switched to 3.11.8 and works perfectly. Perhaps an issue with alt library?
