Renaming y-axis of stackedplot in MATLAB

Hi, here I just import some stock prices for Apple (which is inside the Apple.mat file in the first line) and do a few calculations in MATLAB. I plot stock return vs time using stackedplot, however I can't figure out how I can rename the y-axis to something else rather than Column1. Can anyone help me with that? (sorry this sounds like an amateur question).

I attached the pic of the graph as well as the Apple.mat table here. Thank you so much!

load('Apple.mat');

% Name of loaded table is AppleDailyPriceHistoryTable

% 'Ascending' sorts dates from oldest to newest (2017-2021)

% 'Descending' sorts dates from newest to oldest (2021-2017)

% Either sort the table in ascending order using the code below or manually in

% the variables menu. If already sorted then skip

% Apple_descending=sortrows(Apple_ascending,1,'descend');

t = AppleDailyPriceHistoryTable{:,1}; % extract first column = dates

st = AppleDailyPriceHistoryTable{:,2}; % extract second column = prices

STplot = stackedplot(t,st);

STplot.XLabel = 'Exchange Date';

% Calculate rt. (Extract from the table will return a cell array, which can't

% be used for numerical calculations).

% rt is in decimal form, not percentage form.

for i=1:1:(length(st)-1)

rt(i,1)=st(i)/st(i+1)-1;

end

dt = 1/12;

mean = sum(rt)/(length(st)-1);

mu = mean/dt;

sd = std(rt);

sigma = sqrt(1/dt)*sd;

% mean = 0.001565 = 0.1565%

% sd = 0.020558

% sigma = [0.0712144108966816]

% mu = [0.0187856732853678]

(I'm not entirely sure why you're using stackedplot if you only have one plot, you might consider just using 'plot' but...)

You can use the DisplayLabels property on a stackedplot to set the labels:

s=stackedplot(rand(30,3));
s.DisplayLabels={'Apple' 'Banana' 'Microsoft'};

Thank you so much, this works flawlessly!
