Because of this, there are separate configs for the [Axis](http://d3plus.org/docs/#Axis) class used to display the text ([axisConfig](http://d3plus.org/docs/#ColorScale.axisConfig)) and the [Rect](http://d3plus.org/docs/#Rect) class used to draw the color breaks ([rectConfig](http://d3plus.org/docs/#ColorScale.rectConfig)). This method acts as a pass-through to the config method of the [Axis](http://d3plus.org/docs/#Axis).
