Desktop Survival Guide

Interacting with Plots

Rattle will use what is called the Cairo device for displaying any plots. If the Cairo device is not available then Rattle resorts to the default window device for the operating system (x11 for Linux and window for MS/Windows). The Cairo device has advantages, one being that the device can be encapsulated within other windows, as is done with Rattle to provide various operating system independent functionality.

The Save button of the plot window (on the Cairo device) allows you to save the graphics to a file in one of the supported formats: pdf, png, and jpg. A popup will request the filename to save to. The default is to save as PDF format, saving to a file with the filename extension of .png. You can choose to save in either .png or .jpg format simply by specifying these filename extensions.
