Dear Sir,
 
I am reviewing a group of patients who had a surgical procedure. The  
histogram of the age frequency has a bimodal distribution. I am trying to  
emphasise this by adding a distribution curve on the histogram.
 
Let's say the ages are 8, 9, 7, 6, 7, 8, 5, 4, 16, 12, 11, 10, 8, 7, 9  for 
example. How can I plot a histogram with a distribution curve on  it?
 
Your help is highly appreciated.
 
Ivo
