How to plot cdf in python

Question

I have got an sorted array of integers and I want to plot a Cumulative Distribution Function for it. However , the nature of data is uncertain , so I think I cannot use any predefined library for it.

So to implement it , I have used interpolation function (scipy.interpolate). I am doing it like this :

def plot_cdf(self,x,y,):
        tck = interpolate.splrep(x,y,s=0)
        y = interpolate.splev(x,tck,der=0)
        plt.figure()
        plt.plot(x,y)
        xlabel("Percentage")
        ylabel("Unavailability slot duration")
        plt.show()

Can it be improved??? Is there any predefined function for it????

What do you mean with "the nature of data is uncertain"? Also, what's the point of `xnew` here, since it remains equal to `x`? — Junuxx, Jun 18 '12 at 14:27
hey this code is a snippet and I mean data can/cant fit into any distribution. — Manish, Jun 18 '12 at 14:34

You plot functions with plot, which is what you are using.
