We need functionality to allow annotations to charts (e.g. free text). We need to annotate our charts with text that is: - not a series value or note - not a category note - has no relationship with the plot data - not a title An example is text outlining the source of the data, We have succeeded in annotating charts with Snap.svg.js but the annotations do not survive the imageDataUrl() function for download (or the svg() function). Axis & series notes won't achieve what we want to do. We need to place free text (for example) at the top-left, top-right, bottom-left or bottom-right of the SVG. Most importantly, it would need to be incorporated in the imageDataUrl and svg methods.
