Re: [CHARTS] Brief monthly overview of the local boards activity
You mean like total amount of posts created/merits shared since creation? I am not sure how that would look like since some local boards were created in 2010 while some in 2014 so it wouldn't really be fair comparison. Or you had something else in mind?
You know much better than me how this statistic stuff works 
It doesn't have to be full comparison between different boards, but we could see dates of creation, activity and number of posts and merits for every year since creation of specific local board.
You can do whatever you think it's best, but if bitmover creates racing bars all that information would look much better.
