Data Explorer Node bug (Numeric column filled with missings)

Hi,

I’ve sumbled across a bug, where the Data Explorer Node does not show any histograms in the ‘Numeric’ section, if there is one numeric column filled with missing values (all values are Null). A minimal example is appended.

I’m using Windows 10 Enterprise 1903 with KNIME 4.1.2.

Hi @JohannesViering,
welcome to the KNIME Forum and thank you very much of letting us know of this bug. I could reproduce it on my computer and have opened an internal ticket! In the meantime, I suggest to use the Missing Value Column Filter together with the Data Explorer to circumvent this problem.
Kind regards
Alexander

Thank you Alexander for the fast reply. The Missing Value Column Filter was the solution I chose as well. Nevertheless, I wanted to report this minor bug.

Best regards
Johannes
