How to allow same function name to be used various ways?

I understand how to achieve this interms of the outputs and code exercuted but how do you allow the pop out box display all different possible inputs such as the plot example I've attached

In mac, the suggestion lists pop up by simultaneously pressing Control and 1. I guess the same will work on windows.

Sorry I don't think I was clear. I meant when I make my own function I can only get one line to come up eg:

Ok. I get it now. If you want such suggestion pop up for your own function, then you need to create the JSON file as described here: https://www.mathworks.com/help/matlab/matlab_prog/customize-code-suggestions-and-completions.html

I have got this working with a live script. Is it possible to get it working with a command line based .m file ?

You can use varargin and then check the inputs

function output = MyFunction(varargin)
if nargin == 1
    value1 = vargin{1}
    value2 = 20; % Some default
else if nargin == 2
    value1 = vargin{1}
    value2 = vargin{2}
end

I think that's the easiest, and what I do. But the official way is to use the inputparser: https://www.mathworks.com/help/matlab/input-and-output-arguments.html?s_tid=CRUX_lftnav

You can customize completions for the functions you've written if you're using release R2018a or later.
