Synopsis
Plot data with FORTRAN‑callable routines to create precise X–Y plots and text labels.
This guide describes Dataplot 70, a program that lets you draw lines between X–Y coordinates and place ASCII text at specific coordinates on a compatible plotter. You’ll learn how to convert data to the proper plotter format, draw axes, add axis labels, scale data, and offset the origin for clean, readable graphs.
The book explains how to handle arrays, process data points, and generate the formatted input needed by the plotting routines. A sample FORTRAN calling program is included, along with step‑by‑step instructions for loading, plotting, and interpreting the output. It also covers common error messages and how to manage data and file handling during a plotting run.- How to prepare data for plotting as lines or characters on a plotter
- Methods to scale and offset the data origin for clear visuals
- Techniques for drawing axes, labels, and tick marks accurately
- Examples and explanations of a sample calling program and workflow
