boxplot 2 numerical values

Hello everybody,
I try to make a chart like below. I want to wish on box plot 2 atributes:

  • age group
  • gender

I tried conditional box plot but didnt get what i want.
I need to show data per gender and age group.
See below a chart i realized in python and seaborn, its the same idea just its a bar plot.

Thank you for your support

Maybe you could adapt this example from the KNIME Hub? It seems pretty similar to what you need.
