STD Deviation library

Hi,

I want to add a new topic about google spreadsheet and particle photon, but I think this conversation is related. So… I need help and guidance from the expert.

I have successfully send temperature data from Particle Photon to Google Spreadsheet.
Now, I want to read back the data from spreadsheet to particle photon, in order for me to calculate the STD (monthly) from the sheets.

I have search in google on how to do it, but the searching result is not as expected.

Can anyone suggest me some ideas that work this problem out?

Thanks.
