Dear all, I wanted to know if it's already implemented to plot two observables against each other with the combination of pyalps.collectXY and pyalps.plot.plot. As an example I would like to be able to plot energy vs. magnetization in an example like MC-07. This mainly arises as a question if I want to use the exchange Monte Carlo formalism (thanks for that, it seems to work great with very little modification to my code). There the optimized temperature set is saved as an observable. If I still want to be able to plot M vs. T I would need the ability to plot two observables against each other. However it crashes in alps/lib/pyalps/tools.py in the function collectXY at the line xvalue = np.array([data.props[x] for i in range(len(data.y))]) Is what I intend to do possible with collectXY? Best, Dominik
