It shows only some timestamps on X-Axis. In that example, I have only 00:00:00, 00:00:13, 00:00:41, 00:00:51 .....for X-Axis in diagram. What I want is 00:00:00, 00:00:01, 00:00:02, 00:00:03 ..... every second on X-Axis.
It seems that the time from your main file might be rounded off to the seconds... which is why we were seeing two 00:00:01s (and others too)... so, in order to combine them, I just rounded it off to the closest second. and Time() is just used for formatting.
