On the detailled stats, the last 60 Days are in fact :

-The last 61 days for Total Credit
-The last 59 days for Credit per day
-The last 61 days for RAC
-The last 61 days for World position by credit
-The last 62 days for World position by rac

Is it possible to adjust that ???

Done.

Caching of charts may cause charts to show wrong number of days until after the daily update.

Thanks Willy.

After the daily Update, It's fixed

There is still a minor problem.
On the credit per day Chart, the last 59 days are ok but the first value of the chart(the oldest) is empty even after 2 daily update

Is this problem still on your todo list Willy or did you forget it ?

Forgot it, and fixed it now.

I got another problem now. The stat I have at the end (last 30 days) are wrong. It shows me date from 2005-08-09 to 2005-09-07.

Same here. And on the credit bar chart I see the correct amount of crunching for Monday, but the dates are also in summer 2005. The 'Accumulated more credit than % of all boinc users' figure is wrong. Maybe it's the percentage that was correct for me in summer 2005, a sort of déjà vu.
