I have graphs of the local temperature, of the status of my vps, of the euro exchange rate - chf, in short, many graphs that I am not going to tell you
I love the graphics and yours are very beautiful

Cheers babo, glad to hear that you like the way the look. I tried many different tools and in the end Google charts proved to be the easiest and most elegant solution, with enough customization options for my needs.
I have created a consolidate version of your data using only Portuguese board information:
I must admit that it looks very good and easy to understand which is always important.
Since Portuguese board is one of the most active ones while you consistently month after month have one of the lowest merit per post ratios, has anyone from your board considered applying for a merit source as I think you could certainly use more of those.
