This code snippet causes segmentation fault:

def plot_result(sim_result):
    sim_axis = sim_result.data().getAxis(0).getBinCenters()
    intensity = sim_result.data().getArray()
    plt.semilogy(sim_axis, intensity)
    plt.show()

However, this works:

def plot_result(sim_result):
    sim_data = sim_result.data()
    plt.semilogy(sim_data.getAxis(0).getBinCenters(), sim_data.getArray())
    plt.show()

sim_result was produced by a SpecularSimulation
