Plotting the average or top percentile latency of an API on the left axis and the number of calls to that API on the right is pretty much standard practice where I work. I would argue it makes things more clear. You get to see exactly how the latency changed as the traffic does, or where more noise is visible because the traffic was low.

Because both scales are using completely different units it's more difficult to confuse the two.
