      Description

      Peter Zaitsev:
      Basically we have the values used directly without any expression.
       
      The better idea is to make sure we're using the relevant functions avg_over_time   if we're looking at average max_over_time if  we're looking for maximum etc.
       
      These ensure we're not just picking one random data point but actually compute the value we want to show to provide the data for the interval data point on the graph represents.
        
      I would only have exception in Advanced Data Exploration Dashboard where we want to show as "raw" data as possible. 

      e.g.
      Dashboard "PXC/Galera Graphs" -> Graph "Galera Replication Latency"
