How to change x-axis in Grafana

Hello! I use influxdb as main database to show metrics. So the question is: How can I change the value of x-axis. It shows the time it was uploaded to database. I want to use my own timestamp that i have in database.

this is not possible, InfluxDB has a built in timestamp filed, you need to use that time field

Can you give me advice. How can I solve this?

And can I connect PostgreSQL to Grafana? Thank you for reply)

Use the built in time field in influxdb when you write data
