Dynagraph 1.3
User's Manual

Introduction

Dynagraph is a 3D plotting utility for the X Window System. It draws 3D curves and surfaces representing mathematical expressions and numerical data, and allows for interactive rotation, zooming, and other manipulations of the displayed images.

Dynagraph is intended to be compiled and run within a Unix environment and under the X Window System. It has been tested on Linux, Sgi Irix, and Sun Solaris platforms.

This manual corresponds to Dynagraph version 1.3f, released in October, 2003.
