How to process multivariant questions in Orange can you explain how to process multivariant questions in Orange? For example: 
I have sociological survey database. Among the others there is question:

How would you like to spend your weekend? (pick only 3):


At home 
With friends 
With family 
At work


And here is database example:

 

Database logic: max three options to pick - 3 columns. Respondent answer's order doesnt matter. Is there a possibility to make frequency histogramm in Orange based on these three columns?
Since you say the order of picks doesn't matter, I think your data will be more easily manageable (in any tool, including Orange) if you first transform the database into a wide table of one-hot encoded features, with every option its own column:

id    weekend_home    weekend_friends    weekend_family    weekend_work
1     1               1                  1                 0
2     1               1                  0                 0
3     0               1                  0                 0
4     1               1                  0                 0
5     1               1                  1                 0
