Good morning,
I have a huge amount of data I need to sort and make some plots of. For that purpose I need to find the frequency based on two criteria (so basically a matrix).
I'm familiar with how to set up a matrix-formula to determine the frequency depending on a single array of criteria, but I'm unable to make this work for two criteria.
I've attached an easy example of the problem.
Can you please help me to get this working?
Thank you.
Best regards
Jonathan
