Hi, this brings back cellular usage statistics, using hellocharts lib -- not sure about the previous implementation, there was just a button remaining from that. I chose hellocharts because of it's looks, performance and functionality. I'll try to implement some history data views using it as well -- if there are no problems with the lib. Please test and tell me... https://github.com/openvehicles/Open-Vehicle-Android/commit/a48d3f7bfbe206f3...
