Has anyone tried https://www.chartmyself.com or similar online charting? It looks fabulous, as you can search charts, overlay charts, etc. But I'm not keen on having my personal data online. I may try it just for food allergies, as that wouldn't flag me as a weirdo lol. Does anyone have suggestions for charting? I've done spreadsheets with graphs and such, but they are limited in usefulness. Thanks.
