My name is Lynn Ellen and my website is www.lynnellen.com
 
My height is 5'3" and I weigh 370.  This photo was taken in September of 2006. 
As an advocate of Health at Every Size and I am proud of my fat body. 
I'd like to make a suggestion for the layout of your chart.
 
there is a function in Excel that allows you to keep the top row and/or
the left side row in view regardless of where you scroll on the chart.
although your chart isn't created in Excel, is there a way to do this,
as I had a hard time finding my cell to see if it was filled.
alternative, you could reprint the heights and the weights on the top
and right side of the chart.
