Association Rules widget: Cannot select Max items=1 and cannot export all rules

[minhpth]

Hi Orange team,

I'm using the Association Rules widget and having 2 following issues:

• [x] What's wrong?

1. I want to find a very simple association rule with 1 antecedent and 1 consequent (i.e. rule length=2). However, the widget does not allow me to set the Min and Max items to 1. Instead, I have to set Min items to 1 and Max items to 2, but this setup creates a lot more unnecessary rules for my simple case.

2. After running the widget, I want to export and analyze all the association rules. The only way to do it is to export the results as HTML then copy it to Excel. However, the HTML report does not contain all the association rules in it (the "+1279 more" is not clickable).

• [x] How can we reproduce the problem?

• My data: market_basket_analysis_retailer.zip

• My workflow:

• File widget setup:

• Association Rules widget setup: see the first screenshot in section "What's wrong?"

• [x] Which version of Orange are you using? How did you install Orange?

• Version: 3.27.1

• Installed by Anaconda: conda install -c conda-forge orange3=3.27.1

• [x] What is your operating system?

• Windows 10 Education 64-bit (10.0, Build 18363)

Thank you very much and best regards, Minh PHAN

This issue has been solved by in #36. The suggested features will be available with the new release.

@ajdapretnar, you can probably close this one now. Or are we waiting for the release and we close it then?
