Exponential equation in a graph

I have a code that gives me a plot which looks like a exponential curve. The thing is i want to show the exponential equation in the figure like we do in excel. Can anyone please help me with that?

I tried the basic fitting and there are not options for exp fit.

what exactly does your exponential model look like (and your plot)?

Well, if you have already coded your plot, what is the problem to create a figure in matlab?

If you have your arrays of x and f(x), which is your exponential curve, don't you use figure and plot?

x = yourXarray;
f = yourExpFunc;
% x and f must be the same length.
figure
plot(x, f);
title('your Title');
xLabel('x label');
yLabel('y label');

Approaches for 'basic fitting' or 'options for exp fit' as you mentioned do not produce figures as excel. They only work on the math.
