I have a simple csv with a field for Ram Used. I want to track potential memory leaks  
If I plot the average of this field in Timelion, I get these weird spikes at either end of the graph. Probably because there is no data beyond these endpoints.

I uploaded a screen shot, let see if it actually posts.  
Why do I get these and more important, how do I get rid of them

Hmm, I'm not seeing the same thing locally. When you hover over those end points does it actually show data?

What do you have your date range set to?

Thanks for responding. I am not seeing this anymore. I don't know why.
