Could be but it's not a meaning of the word I have used. Exponential is very much where the rate of change is increasing (or decreasing) so graphically it follows an ever increasing curve rather than a straight line with a slope where the rate of change is relatively constant (which is what I am seeing in our data)
It's plotted on a log chart. So, straight line => exponential.
Suggest you look again!!
