Trends_Log

[buuuudzik]

This is little example for calculating average value:

Code:

require('trends')

-- get data for the last day from 00:00 to 23:59
dates = {}
dates['start'] = os.date('*t')
dates['start'].day = dates['start'].day - 1
dates['end'] = os.date('*t')

-- fetch previous value
daily = trends.fetch('Wind', dates)

sum = 0
for k,v in ipairs(daily) do
 sum = sum + v
end

average = sum/(#daily)
log(average)
