I have high blood pressure (hypertension). I take two readings in the morning, and two at afternoon or night.

I use a script for gnuplot to plot the systolic|diastolic|heart rate|blood sugar
set grid
#set size ratio -1
set title 'Blood Pressure and Heart Rate'
set xlabel 'Time (military)'
set ylabel 'Blood Pressure (mmHg)'
set y2label 'Heart Rate (bpm)'
set datafile separator whitespace
set timefmt "%Y.%m.%d:%H%M"
set xdata time
set format x "%Y.%m.%d:%H%M"
set xtics rotate
plot 'data.txt' using 1:2 with linespoints title 'Systolic Blood Pressure' lt 1,\
'data.txt' using 1:3 with linespoints title 'Diastolic Blood Pressure' lt 2,\
'data.txt' using 1:4 with linespoints title 'Heart Rate' lt 3, \
120 ls -1, 80 ls -1, 60 ls 0
And the data for example
# %Y.%m.%d:%H%M systolic diastolic heart_rate blood_sugar fasting/random

I wanted to save time, and thanks to all I can now just run the script to get the dates, I will add the ":", the %H%M , and the readings. I will be set.
Just copy + paste.
For instance I can use this website
https://hostcat.fhsu.edu/cdclark/static/apps/gnuplot/
To view in realtime and show the doctor the readings.
Best Regards,
Antonio
