I tried to plot a histogram and pdf of my data (data file attached 1.dat). When i see the figure (attached file test.png) , i see y axis more than 1 (although it should not when i use normed=1. I am not getting why this happens.

Somebody kindly write me i) Why the y-axis scales more than 1 ii) after plotting histogram and pdf, how to delete the histogram and show only the normal curve.

The following are the commands i used.
y = normpdf( bins, mu, st)
plot(bins, y, 'k--', linewidth=1.5)

hist plots a distribution whose integral is 1.
