Support for annotations for use with average line.

[jcvw75]

I am referring to this plugin, https://www.chartjs.org/chartjs-plugin-annotation

I would like to see it integrated so I can use it like I use chartcontrol for the winforms, to get the average line.

If there's another way to do this without this plugin I would be glad to hear.

Noted. I'll look at this component and how I can integrate it.
