Graph seems to be not accurate

Hello,

I don't know what to trust, but the gping shows something different than ping command with 0.25s interval
From what I understand when there is no response from the server for about 2s Gping adjust chart to that timeframe but then it does not go back displaying 300ms as few seconds latency.
Gping version 1.3.1

Here is the Video showing the problem
the problem starts at 0:45
