This is possible with the FPScript functions ValuesInInterval and Integral. With the ValuesInInterval function you calculate the values of one day. After that you can calculate the area under the curve using the function or the Area under Curve analysis object.
Example:
Integral(Data[ValuesInInterval(data.x, '19.05.2010 00:00:00', '19.05.2010 23:59:59')])[-1]
If you want to calculate the area under the curve for different days you could add a loop and collect the results in a variable.
Dim resY, resX, lastDate
Dim firstDate = data.x[0] // data is the name of the signal
firstDate = Date(Month(firstDate), Day(firstDate), Year(firstDate))
Do
lastDate = firstDate + '24:00:00'
resY := Integral(Data[ValuesInInterval(data.x, firstDate, lastDate)])[-1]
resX := firstDate
firstDate = lastDate
While lastDate < data.x[-1]
Signal(resY, resX)
