How to combine rate and total

Here I have a graph that shows traffic per interval:

Having InfluxDB calculate the total traffic per interval (window period) is great because I can just go to Legend > Values and add the Total value which then shows me the total traffic for the chosen time range. I can even select a time range to zoom in and immediately see the traffic for that time range.

Unfortunately with this setup the Y axis scale becomes meaningless because it is the traffic rate in bytes per window period instead of a useful bytes per second value.

Can I somehow have both, bytes per second on the Y axis and still have total traffic for the time range?
