How to Build a Time-Series Graph in Grafana to Visualize Data

Are you having trouble making time-series graphs in Grafana?

In this tutorial, you’ll learn what time-series graphs are and how to use them in Grafana using TimescaleDB and PostgreSQL. We’ll cover how to create basic time-series graphs, but also go over how to create multiple graphs in a single panel using TimescaleDB’s time_bucket and time_bucket_gapfill functions. As a bonus, we’ll go over the experimental LTTB function that samples data and allows you to retain visual similarity with the original graph.
