Histogram legend shows pre-filtered items

[Chocoder]

Hello, I love this librairy and I do not know if this issue is a bug or new feature...

My issue: I realized that even after using the raw filtering widget on some datatable, for example on a specific category item, all category appear in the legend of an histogramme widget I add after this very step.

In a table view I see the correct filtering, but as I may have 10 or more items in the initial table it makes the histogramme legend overcharged with useless items...

Is there a trick to show a legend with only existing items?

Maybe the issue exist also on other graphic widgets where I ask a color by category option?

Thanks,

hello @janezd ! First thanks for the very fast anwser! I tried this very widget and it works perfectly! I'm newbee in Orange so I guess I'm not aware of this kind of tricks yet...
Moreover do you know if SHAP visuals are "hidden" in some widget or if this kind of visual could be an additionnal feature I could ask for?
Thanks,

I'm not familiar with it, but is it anything like the widgets int this add-on? https://orange3-explain.readthedocs.io/en/latest/

@janezd yes!
Sounds exactly like what I had in mind! I did not see it in the Widget Catalog, do you know who could update this very page to offer more visibility to this great work and coding?
Thanks again,

@Chocoder You are right, the widget catalog for Explain somehow doesn't appear in the list. Thanks for pointing this out. We will fix it.
