title: Finding the max value in Power BI Column
body: <p>I am sorry for bothering you with my issues and I am totally aware that this is probably pretty easy to solve. I also already searched the Internet but I am not able to apply the things I found.
  I am totally new to PowerBi but need to fix this issue real quick.</p>
  
  <p>So when I go to "Edit Queries" I have different tables on the left.
  In one of them I've got one column for date, one for time and one for power output.
  Now I want to find the highest value in "power output" and show this value and the date and time on the dashboard. What is the best way to do this? Add a new column? Add a new measure? And how do I do this? Which code do I need to use?</p>
  
  <p>I really trying to learn by myself but I have literally no idea.
  Please consider that I probably won't understand any technical terms..</p>
  
  <p>Thank you very much.</p>
