@badger101 I think the easiest thing to do would be to find a Python code on the net for Matplotlib or Seaborn which are included in the bundled Python of KNIME - and then adapt the code to fit your needs like in these examples. Also If you could provide sample data it might be easier to create a workflow that does what you want.

You can also turn that into a dashboard with flexible settings if you want (link to video in the article):
Similar approaches can be done with R - so if you have a code for ggplot2 that also might work
