I am working on some graph stuffs and stuck at a point.
I am trying to plot a histogram using simple :
*import matplotlib.pyplot as plt
but i want to know
1) what is the value of a particular bar in histogram and also want to print
in on output image along with the bars ( either at top of bar or at bottom)*
*2) How to give input of 2 types of dataset in single hist() command , so
that i can compare 2 different dataset side by side on my output image. ( i
dont want it on top of each other as given by the command *histtype*: [
‘barstacked’] and also i read some example in matplotlib site, but they
are for random numbers : something like this:
x0 = mu + sigma*P.randn(10000)
x1 = mu + sigma*P.randn(7000)
x2 = mu + sigma*P.randn(3000)
n, bins, patches = P.hist( [x0,x1,x2], 10, histtype='bar')
but i need this comparision for some dataset.
