Time/hours dimension table not working

[SvenP]

Hi experts,

I am preparing a dashboard for controlling car park operations. I would like to put in a matrix visual that has hours (00:00 - 23:00) on the vertical axxis and Days on the horizontal one. That way I can create a kind of heatmap with repsect to (un)popular times.

I have created a time dim table (00:00 - 23:00) formatted HH:mm) that is linked to my fact table that also has a column where i converted the entry times into full hours by rounding down. That way i get a 1:many relationsship with a cross filter direction "both" (I have tried "Single" too without success.

My issue is that once I put data from my fact table into the matrix, the vertical axis with the hours disapppears. I have added a few screenshots below. 

I am sure something is off with the relationships.

Thanks a lot!

Regards, Sven

Hi @SvenP ，

What is First Weekday in your second screenshot, a measure?

Better to share your pbix to us if you don't have any Confidential Information.

THanks for your response @Anonymous !

Unfortunately, I cannot share the data for confidentiality reasons.

The "First Weekday" is just a column from my dataset that shows the weekday of a record. So it is not a measure.
