Interactive figures

Stacked histogram:

https://discourse.holoviz.org/t/stacked-histogram/6205

Boxplot is fine:

df_melted = res.bins.melt()
df_melted.hvplot(kind="box", y='value', by='variable', c='variable', invert=True, xlabel="variable", ylabel="value",
                 cmap=colors_hex[::-1], legend=False, 
                 width=500, height=500, padding=0.4)

Start with the linked Discourse discussion about the stacked histogram and compare its requirements with the provided Python hvplot boxplot example. The issue does not name implementation files, tests, or a precise interaction design; done would require an agreed stacked-histogram figure that complements the shown boxplot.
