All my CCRs I have these kinds of issues.
Can anyone tell me why this occurs?

Thanks

We have the same
We need a response from Mikrotik about this issue.
In my experience, this can happen when some of the traffic to or from your winbox client is being dropped. For example, during a bandwidth test you might not get any results to graph.
I see that your ping is fine. Did you try monitoring with SNMP? The built-in winbox Graphs are super simple and have many drawbacks. SNMP will be more precise. Winbox Graphs are not meant to be any scientific measurement tool.
