Script examples gallery - Annotation

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 1

annot1

This example has an annotation with location expressed in scaled units.

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.
