Annotations are a key component of a well-executed graph. Used judiciously, text and drawing objects add impact and clarity by focusing the viewer's attention on the essential elements of your graph. Origin provides a suite of general purpose annotation tools for adding text and drawing objects to graph, workbook and layout windows. These annotations can be simple static objects; or, with the addition of a bit of LabTalk script, they can be dynamic objects that -- when activated by some user-specified event -- perform a calculation, import data or update a graph.
