Returning the hour with max count(values)

Hi!

I am trying to get the hour for each day where I have the max ammount of, say, occurrences.

So, I have a row for each occurrence, containing the day, time and type of the occurrence.

I want to show it in a bar graphic with lines "the hour with the max occurrences" for each type.

For example, I have this table:
DAY - HOUR

1 - 8

1 - 8 

1 - 9

2 - 8

2 - 10

2 - 10

I want to show in my graph, for each day the amount of occurrences in bars, and a line of the hour where I had the most occurrences.

Day 1 would be the hour 8, while the day 2 would be the hour 10.

I tried with maxx, summarize, calculate, but with no success.

How can I do it?
