How to reset trends and history data?

[Inc0]

Hi all,

I'm probably blind or I haven't slep enough tonight but i can't find where to reset trends data.
I just changed data unit (from B to b) in some items i use to plot the bandwidth usage and I need to reset the data (history and trends) stored till now to be able to plot a graph with correct values but I can't find where to reset the trends.
To reset the history I'm:
- going to configuration->host
- selecting the host
- slecting the items I want to reset
- at the bottom of the page i select "clear history for selected"
- press "go"
...but how am I supposed to delete trends data?

Thx

in item configuration -> delete history button in the middle of the config area

you need to do that for every item or DELETE directly from database - history_uint table
