F.A.Q
1. How often counter image is updated?
Counter image is updated every hour.
2. How often statistic page is updated?
Statistic page is updated every 30 minutes. Statistic data itself depends on google analytics data updates frequency.
3. Then I created image counter it returns nothing?
Because counter image first have to be generated, it will take short time of period to appear. Just wait a little bit.
4. Then I open chart window it shows data witch is older than 30 minutes?
Chart data itself expires during 30 minits. But if after that there was no request for chart data it is not updated until next request. So if you open chart window from morning and none before you was not opened it, you may need to wait about 5 minutes to get updated data. Same behavior applies to counter.
