---

> This plugin needs to be registered. It does not function as inline plugin.

---

For Chart.js 3.7.0 to 3.9.1 support, use [version 2.2.1 of this plugin](https://github.com/chartjs/chartjs-plugin-annotation/releases/tag/v2.2.1)

For Chart.js 3.0.0 to 3.6.2 support, use [version 1.4.0 of this plugin](https://github.com/chartjs/chartjs-plugin-annotation/releases/tag/v1.4.0)

For Chart.js 2.4.0 to 2.9.x support, use [version 0.5.7 of this plugin](https://github.com/chartjs/chartjs-plugin-annotation/releases/tag/v0.5.7)

This plugin draws lines, boxes, points, labels, polygons and ellipses on the chart area.

Annotations work with line, bar, scatter and bubble charts that use linear, logarithmic, time, or category scales. Annotations will not work on any chart that does not have two or more axes, including pie, radar, and polar area charts.
