How can I extract function evaluations that happen during iterations (fmincon) ?

I am using fmincon and I would like to see/store the values of the objective function and my 3 variables during iterations, not just the values at the end of each iteration - is this possible ? I can see that there are multiple function evaluations per iteration and would like to store and then plot these values :

The only way I know to do this is to have your objective function either display or write the values as it calculates them. The usual way to extract information from an optimization solver is to use an output function, but output functions only report the result at the end of each iteration, not all internal calculations.
Good luck,
