Is tasks a measure as well?
A calculated field similar to the following might help:
window_max(sum([Number of Tickets]))
Then, right click on this and select Compute Using-->Table (Across)
Yes Tasks is a measure as well, but it could also be a dimension. This is where my trouble lies how to get BOTH metrics labeled and just have ONE Mark per column (month) . The Mark is plotted based on the count and month, but I also need the number of tasks or type of ticket for that Mark.
Key to above logic is that the Mark represents the type of ticket (ie, # of tasks in ticket) with the highest frequency in that month.
Just one more piece of information. I can get the above without a table calculation, but showing all the marks for all the ticket types. I just want to show the top most mark which represents the highest count. I have tried using variations of window_max in a custom table calc and just have not found the right formula to get the desired result.
