Right now we only have this data for three regions: EUW, EUNE, and NA. Other regions unfortunately do not have this data available.
Additionally, the method we use to obtain the statistics sometimes does not return data for profiles in those three regions due to a bug. Unfortunately this is on Riot's end. They are aware of it and are working on it. If you do not have data for over a week, please contact us so we can add you to our list of summoner profiles that are experiencing this issue!
