Ctioga is a powerful command-line plotting system, to rapidly make publication quality graphs. Ctioga is based on the wonderful work by Bill Paxton, Tioga.

Ctioga has been designed with ease of use and extensibility in mind. It is based on the powerful Tioga plotting library.

Requirements:

· Ruby (at least version 1.8.2)
· pdftex

Installation:

First, unpack both the archives you did download. A mere

tar xvzf file.tar.gz

on both files should do it.

There are two ways to do the actual installation.
With administrator privileges
If you have administrator privileges on your computer, you can try the following:

cd tioga-1.1.7
sudo ./QUICK_INSTALL
cd ..
cd ctioga-0.5
sudo ./INSTALL

where you need to replace the dots by the actual name of the directory extracted.
Unprivileged user
Without privileges, you might want to try this

cd tioga-1.1.7
./HOME_INSTALL
cd ..
cd ctioga-0.5
./HOME_INSTALL

However, in this case, as the installation scripts should remind you, you should set the RUBYLIB environment variable appropriately. For instance, if your login shell is bash (the standard on most of Linux distributions), add the following lines to the file .bashrc found on your home directory:

RUBYLIB=$HOME/lib/ruby
export RUBYLIB

What's New in This Release:

· This release has many new features, such as a comfortable way to organize several different plots on one object, the ability to make free-form graphs, and much more control in the look of axes, including the ability to display axes with a non-linear mapping.
· Several bugs have been fixed.
