Summary
PLOT3D is a program written in LAP6-DIAL (dated October 1971) designed to display and plot data stored on LINCtape using an XY plotter. It provides a three-dimensional effect by layering data blocks without overwriting previous ones.
Key features include:
- Data Handling: Supports both single and double-precision data, with user-definable spacing between data blocks.
- Modification: Offers interactive data modification capabilities, including scaling, filtering (simple 3-point averaging), data magnification, and subtraction of constants via hardware switches or teletype commands.
- Plotting & Labeling: Includes a "Type Routine" based on a Bristol Subroutine, allowing users to label plots directly via the teletype, with options for character sizing, rotation, and inversion.
- Operational Control: Uses a combination of hardware sense switches and teletype input to manage loading, plotting flow, and display parameters.
