You can create a barchart like this:
from matplotlib.pyplot import *
x = [111,122,155,192,11,123,120,]
y = [3,4,3,5,9,10,23]
bar(x,y)
show()
gives:
Using hist() bins your data for you, so you would pass it your raw data, ie. it would look like this:
data = [111, 111, 111, 122, 122, 122, 122, 155, ...]

@abhisek - The above plot is a histogram.

i dont need any info about bar diagram. Please give me the codes for histogram only.

@abhisek - In an histogram the area of the bar is equal to the frequency of that data. It can be drawn as a barchart. Your data (appears to, although your question is unclear) contains frequency infomation, so the easiest way to plot it as a histogram is to do the above. I also explain that if your data is raw, you can use
hist() and it will generate the histogram for you.
