Hi , I need to add one more field "row_num" in the same timechart
Search query is 
index=abc |  timechart span=1hr   avg(response_time) by  host 
row_num contains 30 ,40,25,15,.....
Thanks.
Thankyou all for the responses .Somesoni2 and woodcock , i am getting the timechart for both response_time and row_num  but not as expected . 
I am looking for is 
when i hover into the chart , it gives
1)date and time 
2)avg(response_time) with values .
can max(row_num) also included along with the other two when i hover ?
 
					
				
		
With my answer (the "chartable" one), you will get TWO lines for each host: 1 line for the avg(response_time) and another for max(row_num).  There is no way to stuff 2 separate values into a single line (see the "unchartable" commentary in my answer).
 
					
				
		
If you are going to use the visualization tab, you need to make sure that all of your "things" have a single numerical value.  You can gather as many "things" as you like just by adding them in a string like this:
THIS IS UNCHARTABLE:
index=abc | timechart span=1h avg(response_time) values(row_num) BY host
THIS IS CHARTABLE:
index=abc | timechart span=1h avg(response_time) max(row_num) BY host
 
					
				
		
You want to include avg(row_num) and it should be calculated for each host? IF yes, the this should work.
index=abc | timechart span=1hr avg(response_time) avg_response_time avg(row_num) avg_row_num by host
Update
Does this give you what you want?
index=abc | eval host=host.":".row_num| timechart span=1hr avg(response_time) avg_response_time by host
 
		
		
		
		
		
	
			
		
		
			
					
		Might need "chart OVER BY" instead of timechart? Or a fancy stats call. More information about what exactly you're looking for would be helpful.
 
					
				
		
What information is the row_num field supposed to convey?
Are you wanting the average of the row_num for each host in each hour, or the max, or what?
