Is there a graphical data counter for Ubuntu that records how much uploaded/downloaded data was used and bandwidth being used and total amounts, filtering it by application?
You can use the program nethogs from the standard repository for this.
sudo apt-get install nethogs
sudo nethogs (it requires root privileges to run)
This tracks the network usage of all processes while it is running. When it starts it shows the current rate at which everything is sending/receiving, but you can press 'm' to switch it to cumulative amounts (and further times to display it as kB/B/MB). It will split sent/received data as well as show you a cumulative total across all processes from the time at which it was run.
