how to smoothen graph

i have like ten readings. i am trying to draw a x-y graph. but it gives a sharp edged graph at the connecting points. how do i smoothen it. i tried the exponential fit but it is not working.
thanks,

Smoothing data in a way that doesn't distort the underlying information can be a very non-trivial task. The first thing I would recommend is to "hit the books", actually one book in particular:

"Exploratory Data Analysis" by John W. Tukey

This book deals with data smoothing extensively with a number of different types of examples. Once you understand the principles involved, writing routines to actually do the smoothing is very easy--Plus I can provide some that I use myself.

For a copy of this book check any good engineering library, or ask a statistician friend if he has a copy of "the red book".

Try the Savitzky-Golay Smoothing Algorithm. There are numerous
sources, I found it in Numerical Recipes for C.
