Why I can not input data to InfluxDB Cloud

I input data manually and notify success, but when I query, not any data showed.
Please help me.
I input manually by below lines:

Where/How do you query?
Is the time window chosen correctly? Otherwise you will not see any data.

I query in this window

You are right, Not show data because time range for query, thanks thanks

The reason why you don’t see any data is that the time window is wrong. On the right side of the window you selected “Past 2d”, but your data is older when I look at the timestamp?
Unfortunately, if the time window is not selected correctly, no data is displayed, which is quite irritating for beginners.

Yes, because I copy sample data from exercise with time format nanosecond (dont know exactly date) and forget this problem is here.
Thanks so muck guys.

I was able to get past this problem by saving the pasted data to a text file with a .line extension. The window you paste the data into may not correctly parse line endings. The start and end timestamps are:

2022-01-20 12:00:00
2022-01-20 12:04:45

I wrote a small python utility to convert them

from datetime import datetime

def format_my_nanos(nanos):
dt = datetime.utcfromtimestamp(nanos / 1e9)
return ‘{}{:03.0f}’.format(dt.strftime(’%Y-%m-%d %H:%M:%S’), nanos % 1e3)
