Chapter 1. Introduction

LabPlot is a program for two- and three-dimensional graphical presentation of data sets and functions. LabPlot allows you to work with multiple plots which each can have multiple graphs. The graphs can be produced from data or from functions.

All settings of a complete set of plots can be saved in a project files. These project files may be opened by command line parameters, using the File menu, or by drag and drop.

Every object (title, legend, axes, axes label) can be dragged with the mouse. A double click on an object opens the corresponding dialog to change the options of the object.

The settings of a plot/graph may also be changed using the Appearance menu. With the Edit menu additional data sets and functions (graphs) can be included which can be displayed in the same as well as in different plot.
