Blood sugar measurements

Hi hope someone will help. I need a spreadsheet that shows date.time and twice daily sugar measurements .

Does this from the extensions site help? https://extensions.libreoffice.org/en/extensions/show/body-parameters-monitor

Maybe this question which has a sample, how do I do a blood/glucose curve?

Or this question, How do I change part of the background on a (blood sugar level) line chart - #5 by LeroyG
