[SciPy-user] Density plot

Hi, Can anyone let me know how to make a density plot, more specifically a gaussian-smoothed version of a histogram?  I mean, it's not the plot itself, but to get the maximum count (or highest peak) of the density distribution.   In S plus and R, there is the "density" function which I can use to get the max x and  y in the probability frequency distribution. I was told that, in scipy, there is a kernel density estimator for non-parametric density estimation, and fit the "Gaussian smoothed version of the histogram" when used with Gaussian kernels.  So far I haven't suceeded finding the function. I really appreciate if anyone can help in any way! thank you!
