# How do I set limits and alerts for graphs?

### Why are limits important?

* They control colours, alerts, and trends on your dashboard.
* They trigger notifications when an issue arises.
* They appear on graphs as coloured lines, providing a clear visual guide to see how close your readings are to your set limits.

### How do limits work on graphs?

When you set a limit, it is displayed as a coloured line on your graph. This makes it easy to track fluctuations and ensure your environment stays within the ideal range

Any time you adjust a limit, the change is reflected in the graph from that point forward, giving you a historical record of all limit adjustments throughout your grow.

### Why is this useful?

This is especially valuable for crop registration, as it allows you to review every environmental change made during the grow cycle.

Ever wondered if you maintained the right humidity and temperature when it mattered most? Now, you can check - with a complete visual history at your fingertips for every graph in the app.
