It is very strange. Which analyzer do you using? Try contact your software distributor for more detail debugging.
I noted that I found the similar problem in Scrutinizer. Scrutinizer is counting the long time flow (i.e. 500MB data flow) in the exporting time. So it producing a spice 500MB in one minute instead of distribution of flow in the time.
It is a strange. The configuration looks OK. Can you more debug which flow cause a spike? I.e. web traffic from source A to destination B? Is it one flow or more flows? Try to enable ip top talkers (ip flow-top-talkers) and compare your results with the "show ip flow top-talkers".
If you will find the same results in IOS CLI, the problem is with your line card. If not the problem will be with the analyzer.
"This breaks up long-lived flows into 5-minute segments. choose any number of seconds between 64 and 900; if you leave the default of 900 seconds (15 minutes) you will get spikes in your utilization reports." -- don't recall where I got this quote from.
