[Read New File] Attach Text to Data [-] -
There are two ways to add textual annotations to your graph: data-space relative, and page-relative. The first attaches your annotation to the coordinates of your plotted data, such that, after panning or zooming, your annotation will remain in the same position relation to your data, though it will change its position on the screen or printed page. (Some annotations will actually disappear from view when zoomed into a different region of a graph.) When you press this button, a pop-up window will appear for you to enter some text. After entering your text and clicking the ok button, then click-once at the place on your graph where you wish to attach the annotation. You will see the annotation appear where you clicked. Typically, data-relative annotations are used near data features in your graph, such as identifying individual curves or inflection points. These annotations are placed with the graph borders. The second method is described next.
