I'm very confused to create a frequency histogram in python using matplotlib.pyplot.

I have two list: one is the frequency list and another is category list. E.g:

Frequency list: 

freq = [123,142,543,77866,8,2424,3]

category list:

category = [-1.23,0,2.13,5.4345,7.45,9.00,12.32]

So, each item from freq list relates with the item from the category the same position, e.g: 123: -1.23, 543:0 ...

That's my doubt...

How to using those list in the hist ?

plt.hist(x, num_bins, normed=1, facecolor='green', alpha=0.5)

I'm very confused each parameters i have to use in the instruction..

Could you help me about it?

Here is the sample of hist I'd like to create.

    There are many other duplicates as well. Just search for "matplotlib histogram with binned data" or similar – tmdavison Mar 10 '16 at 22:51
