=============
Configuration
=============
|igraph| includes customization options that can be set via the :class:`configuration.Configuration` object and can be preserved via a configuration file. This file is stored at ``~/.igraphrc`` by default on Linux and Mac OS X systems, and at ``C:\Documents and Settings\username\.igraphrc`` on Windows systems.
To modify config options and store the result to file for future reuse:
.. code-block:: python
import igraph as ig
# Set configuration variables
ig.config["plotting.backend"] = "matplotlib"
ig.config["plotting.palette"] = "rainbow"
# Save configuration to default file location
ig.config.save()
Once your configuration file exists, |igraph| will load its contents automatically upon import.
It is possible to keep multiple configuration files in nonstandard locations by passing an argument to ``config.save``, e.g. ``ig.config.save("/path/to/config/file")``. To load a specific config the next time you import igraph, use:
.. code-block:: python
import igraph as ig
ig.config.load("/path/to/config/file")
