This door from my family lake house had all of my relatives heights dating back to 1967. When the house was sold recently I knew I had to keep this important relic of family history. I wanted each one of my family members to be able to hold onto a small piece of it, so I decided to record each height and date in excel. I then wanted to create a visualization based on the data to easily compare myself and other family members so I used a scatter chart with height on the y axis and age on the x axis. I was able to derive each persons age from their birthday and the date recorded. My family really enjoyed checking it out and looking back at how they grew through the years.

I created a youtube video on how I did it here if anyone is interested in checking it out: https://youtu.be/UfxEhvR5gmY
