Lewin's Growth Charts

Here are a couple charts showing Lewin's growth since his birth. As shown in the key, Lewin's statistics are in blue. They are plotted against the National Center for Health Statistics 50th percentile data in red. That is essentially the "average" weight/height figures. 50% of the "reference population" would fall below those figures, 50% would be above.





These charts should automatically update when we enter in more growth data. I have added a link to this page on the left in the My Links section so you can come back to this page to get updates on his growth. It took me forever to figure out how to produce these graphs from a spreadsheet. The spreadsheet is a piece of work too. Here are some of the formulas that are used, =if(A2,sum(DAYS360(R2,A2,)/7),S2), =if(A2,SUM(B2+(C2/16)),S2), =sheet1!b2. Spreasheets are amazing.
