add text in bins of histogram in wxpython
Question: How to write text inside bins(bars) of histograms in wxpython?

    
    
        import csv
        import matplotlib
        import matplotlib.pyplot as plt
        import numpy as np
        from matplotlib.figure import Figure
        data1 = np.random.normal(5.0,3.0,1000)
        with open('test.csv', 'wb') as f:
        writer = csv.writer(f)
    
    
    
        plt.hist(data1)
        plt.show()
    


Answer: You can't write text inside the bins directly. This is because the bins are
simple Pactch objects.  
However, have no despair! There is a path you can go to achieve this:

  * iterate over bins, get their boundaries
  * create a text label
  * place it in the correct boundaries 

To obtain the bin boundaries see my answer here: [How to color bars who make
