Ploticus includes a facility for including labels,
and arrows. While obviously not the strong suit of a batch-oriented
program, proc annotate can render text,
one or two arrows with semi-intelligent placement, and a backing
box if desired. Clickmap support
is available for annotations.
Example 1annot1![]() This example has an annotation with location expressed in scaled units. Example 2annot2![]() Another example, showing various options. Example 3clickmap_annot![]() This illustrates clickmap support for annotations. Try clicking on any of the boxes above.. Example 4rangesweep1![]() Annotations done in vertical text. Example 5button![]() Proc annotate may also be used to create buttons for web pages. Example 6annot_circ![]() Annotations can be enclosed in ellipses or circles. Example 7devol![]() Proc annotate can be used to circle noteworthy graph areas. Example 8mockup![]() An example of a long annotation. Example 9![]() Click here to see script source. An example where proc annotate was used to create a simple E-R diagram for a database. Entity bubbles support text annotation that appears when the mouse hovers over them, and click-thru to actual database table documentation. Try hovering the mouse pointer over an entity bubble, and then click on the bubble.
This was somewhat tedious to code, since all locations were hard-coded,
and the order in which bubbles and arrows are rendered is important for
clean arrow ends.
