Store the histogram:



In [5]:

    
histogram.to_json(path="./histogram.json");
del histogram

Turn off the machine, go for lunch, return home later...

Read the histogram:



In [6]:

    
histogram = physt.io.load_json(path="./histogram.json")
histogram









    Out[6]:





Histogram1D(bins=(106,), total=10000000, dtype=int64)



In [7]:

    
histogram.plot()









    Out[7]:





<matplotlib.axes._subplots.AxesSubplot at 0x7f5527b47748>

The same one ;-)

Continue filling:



In [8]:

    
# Another big chunk of data
data1 = np.random.normal(3, 2, 10000000)
histogram.fill_n(data1)
histogram









    Out[8]:





Histogram1D(bins=(212,), total=20000000, dtype=int64)



In [9]:

    
histogram.plot()
