How to create a cumulative histogram in Hist?

[txell-1]

Is there a given way to create a cumulative histogram using Hist?
And also, is there a way to create this cumulative Histogram from a given 1d or 2d Hist object?
In Matplotlib it would be this, but in our case some of the functionalities available in Hist are needed.

1D, anyway:

array = np.cumsum(h.values())

If you want a histogram object out, then:

cumsum_hist = h.copy()
cumsum_hist[...] = np.cumsum(h)

You can be explicit and use h.values(), but just h works inside cumsum, as it exposes the interface NumPy expects.
