Purpose: define new features to complete DasAnnotation Audience: Das2 developers.

Introduction

The DasAnnotation object allows annotations to be added to the dasCanvas.

Current State

It is positioned with a row and column, uses GrannyText, and allows pointing at a coordinate.

It currently misses the bounds if you enlarge the font.

Proposed Changes

• This should have a position relative to the box control, similar to the legend.
• The default is NW, but this could also be SW,NE,SE,OutsideSE,Above,Below.
• It would be nice to have rotations and offsets. (NW;+3em+10pt,+2em)
• It would be nice to be able to attach it to data as well, so instead of drawing an arrow, it would locate based on the data.

Current State (2018-06-14)

This was all implemented, excluding rotations. See http://autoplot.org//Annotations and http://autoplot.org//help.annotationCommand

New Proposed Changes

I'd like for annotations to be able to implement plot legends. This would mean adding a new capability to the GrannyTextRenderer to insert plot symbols and colors. See https://sourceforge.net/p/autoplot/feature-requests/634/
