Script to re-generate trends

[Youpy]

Hello,

I understand that the trends are generated every hour.
I wonder if there is another script that could be used to re-generate them based on the existing history ?

Due to a typo in a mysql command, I deleted the trends of several items.

Thanks

I'm also interested in finding out if it's possible. I forgot to enable trends for some important sensors and now I've got 30 days history but can only use 2 days of graphs...
