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. Furthermore you can use a doughnut label annotation which can be used to add contents (text, image, canvas) in the middle area of the doughnut charts.
