How to create a graph without knowing the data points?

Hi

I am trying to create the following graph (exponential when service level goes to 100%) in Matlab (see attached) but can't seem to make it work as I have no data points (function) given.

Note: 'safety stock requirements' is the label of the y-axis.

How can I do this?

Thanks a lot in advance! I really appreciate it!

I am not certain what the exponential function parameters would be (and you had not previously mentioned that it was exponential), so I presented a hyperbola that appeared to match the appearance of the plot in my Comment to your previous Question.

I have replicated your graph. Thank you for that! I am not sure whether or not it is exponential which is why I did not explicitly mention it.

My pleasure!

It appeared more hyperbolic than exponential to me. I experimented with an exponential function and could not replicate your plot with what I considered to be sufficient accuracy.

This does a much better approximation. Choose the value of ‘n’ that works best for you.

The Code —

x = linspace(0, 100, 250);
n = 75;
y = 10^(2*n)./(10^(2*n) - (x+1).^n);
y(y < 1) = NaN;

figure(1)
plot(x, y)
set(gca, 'YLim',[0  5])

It scales and translates automatically so you only need to experiment with various values of ‘n’. The NaN assignments prevent ‘y’-values less than the set minimum from plotting.
