Before you can display performance levels in charts, you have to define and assign them. You can do so before a load test
               execution (proactive approach) or after an execution (reactive approach). 
               		
               
To display performance level conditions in a chart: 
                  		
               
 
               	 
              
            	 
            
               -  
                  		   Create or open a chart. 
                     		   
                  		
               
 
               -  
                  		  Drag measures that have performance levels assigned onto the chart. 
                     		   
                  		
               
 
               -  
                  		  Click a measure in the measure list to activate it. 
                     		   
                  		
               
 
               -  
                  		  On the 
                     			 Series tab, in the 
                     			 Display group, enable 
                     			 Performance Level Conditions. 
                     		   
                  		
               
 
            
 
            	 
            The chart shows colored boundaries for the conditions of the assigned performance level and a small legend describing them.
               For example: If the current performance level contains a condition like P90 < 0.2, the condition is fulfilled if 90 % of the
               graph lie below the shown boundary. 
               		
               
Note: Performance Explorer only shows performance level conditions for one measure at a time.
