You might find a better way to provide your
example than that service. I refuse to answer
the questions it wants me to respond to, just
to look at your picture.

And please explain yourself more clearly,
although if you did explain more clearly, you
probably would solve your own question. What
exponential function will you use? Do you want
the interpolant to go through zero between
every pair of data points?

Why in gods name do you want to interpolate
in this way anyway?
