3 questions on filters & components

Hello all, hope you’re having a great day.

Picture for attention/understanding mostly:

Within my flow, I would like to:

  1. Filter the data by

  • Cluster (a group of country) and/or

  • Country

  • Date (year) and/or

  • Date (quarter) and/or

  • Date (month)

  1. Some filter conditions above are interdependent (i.e. a Cluster will contain a set of countries)

  2. Combine my filters and graphs in a component

I am trying to understand how “Nominal Row Filter Widget” works, however I am facing difficulties to:

  • Combine in a component nodes that are in different “position” in the flow. Ideally I’d like to have my filter conditions on top and the result below.

In the image above I had the items in the blue box as a component, I tried adding the Widgets but it didn’t work.

  • I am also exporting the data as excel which is why I placed my filters before the pivot (excel export not shown in image)

Manage interdependencies between filters. In my example, a Cluster will contain a set of countries and i’d like to avoid having to select both (one should feed the other). Likewise, if I select a year then I shouldn’t have to select the matching quarters or months.

For some reasons I haven’t figured out how the slider works (and many things in KNIME yet) so any help or pointers would be much appreciated.
