Widget Distributions no longer visualizes the histogram.

What's wrong?
I've been using the widget Distributions on my desktop for a few years. Now, it is no longer working. Id est, in ANY workflow I can instantiate it, I can connect a fed Data Table to it. However, when double-clicking on it, I see the controls on the left hand side of the panel, as usual, BUT no histogram appears on the blank canvas, for any feature.
I twice disinstalled Orange and then re-installed it on my desktop. But the widget keeps not working. The same workflows and widget run successfully on my laptop.

How can we reproduce the problem?

What's your environment?

• Operating system: Windows 10
• Orange version: 3.38.1
• How you installed Orange: from your website, no customizations.

Do you perhaps have multiple displays? If so, does the problem go away if you disconnect some of them and start Orange when only a single display is connected?

Also, is this the only visualization with problems? Please, also try Scatter Plot.

Thank you!

Hi Marko, thanks for your prompt answer.
As you can see attached below, Distributions is the ONLY visualization with problems, even if alone in the workflow.
I face the issue with Distributions in any workflow running on my desktop (no problem with my laptop). Even on rebooting PC and restarting Orange.
Please note:

• the weird bar in the Distributions widget, that one can sees when clicking on the blank space of the widget
• I can see the Distribution for the column 'iris', I cannot for any of the 4 features.
  Regards.
  Antonio.

@antoniopiemo Your bars are possibly hidden.

1. Choose a Fitted distribution other than None
2. Uncheck Hide bars
3. Set Fitted distribution back to None

@markotoplak It is a bug: the bar hiding is not turned off automatically when checked and Fitted distribution is set to None and ends up showing nothing but the columns are still selectable.
