Data Distribution

Hello, I have some data and i want to see it in plot that how it is distributed all over, like getting some plot , but the plot command donot give me smooth curve or response i want to see it in curve.Or u can say like gaussian distribution of my historgram like this one

Perhaps you want to use hist() to draw a histogram of the data?

but i want to see the curve plotting on to that histogram

Then perhaps, you would like to try histfit() with some specified distribution.

    histfit(randn(1e3,1),20,'normal')

or use ksdensity()

x = [randn(30,1); 5+randn(30,1)];
[f,xi] = ksdensity(x); 
plot(xi,f);

The Wavelet Toolbox also has 1-D density estimation capability.
