PREVUE is a screen-based interactive display routine for manipulating text on plots. It outputs a plot file pre. The pre file can be read by PLOTX to produce hardcopy plots.

4.51.1. Description

PREVUE enables the user to manipulate test strings in a plot. The plot itself cannot be altered, but may be enlarged or reduced in size during the text manipulation (the output plot size is unaffected by this resizing).

A character string may be moved by clicking on it (which causes it to disappear from the screen) and then clicking on the screen where the string is to be positioned (where it becomes visible). The string is repositioned with the bottom left corner at the mouse release position.

Eight control buttons are displayed at the top of the plot screen.

The output file pre will contain all changes to the text data. Note that PREVUE will not read a pre file unless it is renamed.
