This document is a handbook for using SciDAVis, a program for two- and three-dimensional graphical presentation of data sets and for data analysis.

This manual is organized in several chapters:

-The first one describes the main concepts and terms which are used in SciDAVis.

- The second chapter is a tutorial on how to obtain plots from different data sets. It is the one you need to read first to understand the basics of SciDAVis and to be able to draw plots.

- The three following chapters are descriptions of all the commands, buttons and dialogs used in SciDAVis. These chapters are the reference manual of SciDAVis.

- The two following chapters describe more deeply some specific possibilities of SciDAVis, that is the statistical and mathematical analysis of data, and the scripting.
