Blood pressure needs two readings, a Systolic and a Diastolic reading. Does
any one know how I can display readings that I have kept ove the months of
my own hypertention.

The readings need to give the date, time and the two readings, usually with
a line joining the two readings.

a tipical example of a reading is:

date 11/2/05
time 20.15
sys 130
dia 74

many thanks

Mike
