Text string plotting enhancements for the Tektronix Advanced Graphing II software on the ORNL Fusion Energy Division DECsystem-10

This report documents the user interface to a software library that extends the text string plotting capabilities of the Tektronix Plot 10 Advanced Graphing II (AG2) software. This software, called AGXTCS, permits easy plotting of text strings and labels at user-specified positions and automatically determines a centered location for text strings associated with axis or graph labeling. The AGXTCS software must be used with the AG2 and Tektronix Terminal Control System (TCS) software to create display images on the screen of a Tektronix 4000 series storage tube terminal and/or to produce display images in TKF-formatted graphics files for subsequent postprocessing on other graphics devices. Fully described within this report are the software capabilities, subroutine argument lists, and methods of accessing the AGXTCS software library.
