Is it possible to customize the modbar for a parallel coordinates/categories plot? Or is it something that is not supported? The only button that seems to work for these plots is the export to png.
For example, I would have liked to zoom around a specific category on one dimension to see what kind of edges come in and out.
I tried the following:
import plotly.express as px
df = px.data.tips()
fig = px.parallel_categories(df, dimensions=['smoker', 'day'])
fig.show(config={'modeBarButtonsToAdd': ['zoom2d']})
It does not throw an error, but also does not add the button to the modbar. I also tried all kind of “zoom flavors buttons” I could find here: https://github.com/plotly/plotly.js/blob/master/src/components/modebar/buttons.js
