Thank you for responding.
Because it seemed like the appropriate setting, I do have ‘Use row colors’ checked.
This test was done by following instructions on the KNIME web site in ‘Build a workflow’ which uses sales_data.csv .
My demo project was an attempt to perform the same steps with the addition of the later addition of the Color Manager in the section titled, “Add the Color Manager node:” at the end of your demo. The other difference I see from your documentation is that the lines between nodes are straight instead of curved, but I strongly doubt that’s relevant.
When I first downloaded and installed KNIME the current version was 3.7.2 . Within a few days, I saw the notice that there was a KNIME release 4.0.0, so I uninstalled 3.7.2 and installed 4.0.0 . Is it possible that this sequence is in some way causing this problem?
I didn’t introduce any of my own data or procedural steps, so duplicating your ‘Build a workflow’ demo should replicate the same issue. It doesn’t seem likely that there’s anything different on my computer that would help diagnose this, but I’d be glad to share any files with you that you might need.
