DavidT3 / XGA

X-ray: Generate and Analyse is a module designed to make the analysis of XMM observations simple and efficient. It provides an interface with SAS for the creation of XMM data products, as well as a way to easily perform fits (scalable for multiple observations) and retrieve information about an object, all within a Python package.

When plotting third data axis on scalingrelation (i.e. colour of points) with new deps we get an error #1207

Should be an easy fix - just a change in the matplotlib api i hadn't noticed - specifying the axis to steal space from should return this to usual function.
