Allow the developer to add various annotations to charts specifying position, alignment, color and font information. Also, provide key information about the chart objects such as their position, center, etc..
In our next major release we plan to introduce drawing API, which will allow you to draw custom shapes or other visual elements on the chart canvas. I hope this will be applicable to be employed for other than text annotations.
Unfortunately only text annotations were implemented. Could we see images as data annotations in the future?
This is good. Is there a way of overriding the drawing of notes and instead draw images, text, etc. ? If not, I think it would be great to add a draw function within the notes property. ex: notes: { draw: function (canvas, x, y) { // Do something here } }
Implemented in the Q2 2013 release!
