Superchart history doesnt show, only live

I have the blynk board connected to an Android phone thru the blynk server. Superchart only shows live readings, but deletes history if I exit the app. I just need the binary mode to show how many times the button has been pressed during the week. Also, it does not send me the CSV file thru email. Any Help???

Have you read the section in the documentation that talks about granularity:
http://docs.blynk.cc/#widgets-displays-superchart

If you’re trying to track random button pushes through the day, which will presumably be represented by a “1” in a binary graph, then you’ll need to send “0”s fairly often (at least every minute) to maintain the minimum granularity level.
