ChangeLine is a free Chrome extension developed by ChangeLine that allows you to display a change log for your business as annotations on any graph in your browser. With ChangeLine, you can easily track events from every part of your business and overlay them on graphs to find causation and keep your business moving.

Whether you're wondering "What happened there?" or "Why did that graph spike?", ChangeLine provides the answers. You can drop JSON data directly into the extension to get started right away. Additionally, if you want to build and save your company-wide change log for later use, filtering, and collaboration, you can create an account at ChangeLine.io.

The extension enables you to inject your data into the overlay, allowing you to view it as annotations over a graph in your browser. You can easily adjust the overlay by dragging it to the start of the x-axis and resizing it to match the graph using the provided guidelines. By hovering over the timeline ticks or event cards, you can quickly highlight corresponding elements and view multiple events simultaneously.

ChangeLine is a powerful tool for businesses, offering basic functionality for free. In the future, advanced features will be available through a subscription. Start using ChangeLine today and gain valuable insights into your business events!
