No data Points on Chronograph dashboard

I imported a file into InfluxDB database which had following data as mentioned below. the connection was also established with the database. When i run a query on Chronograph, i dont see any data point. However i am able to see the graphs when i do it with a different database such telegraf. I dont understand why there is no metrics exported to Chronograph when i import a table to influxdb database.

CREATE DATABASE NOAA_water_database_1

I’m not sure, but maybe the points imported are earlier than the time range you are viewing?
