How do you chart a single data field?

I'm trying to just chart the NTP offsets from the Loopstats file.
Here is a sample of the data source:

Day   Seconds    Offset        Drift    Est.Error    Stability  Polling.Int

56639 6177.359   0.004032319   -25.301  0.001841655  0.117440   6
56639 6348.131   0.004225549   -25.258  0.001724064  0.110906   6
56639 6698.364   0.002325595   -25.210  0.001747019  0.105151   6
56639 6877.378   -0.001154758  -25.222  0.002045648  0.098456   6
56639 7024.343   0.001006711   -25.213  0.002060481  0.092150   7
56639 7994.357   0.003429927   -25.164  0.002109237  0.087962   7      
56639 7998.387   0.003124573   -25.164  0.001975962  0.082281   7

So I've extracted each of the fields accordingly and all I want to do is chart the Offsets, which is the 3rd data field in the sample above. I tried: | chart sum(offset) by seconds, but that doesn't yield a nice line graph, which is my goal. Any suggestions?

If your goal is to chart the values in the offset field against the corresponding values in the seconds field, you don't want to sum(offset).

<source> | chart values(offset) by seconds

An issue to realize is that it is possible to have multiple values of offset for a single value of seconds since this is a comparison of the two data sets not based on a timeline.

Thanks. The "values" under charts is exactly what I was looking for, Thanks. I got to focused on sum, avg, list, etc and somehow overlooked 'values'.
