Here is a neutral, objective, and interesting 1-paragraph summary of the text: To compare metrics over time, developers can leverage PostgreSQL's LATERAL JOIN function in combination with TimescaleDB and Grafana to visualize timeshifts. This technique allows users to easily analyze how metrics change over time by comparing current values to those from previous periods, such as days, weeks, or months ago. By using a single graph with multiple lines representing different time intervals, developers can gain insights into trends and patterns in their data, making it easier to identify seasonal fluctuations, anomalies, or other changes that may indicate underlying issues. This approach can be applied to various use cases, including monitoring IoT devices, tracking website performance, or analyzing user behavior, providing a powerful tool for data analysis and visualization.
