How do I display a plot based on the user input value?

The .mat file usage.mat contains yearBuilt, names, yearReconstruct, and score.
clear;
close all;
userInput=input("Please choose between the following numbers: 1,2 or 3.");
Test("usage.mat",userInput);
function Test(usage,userInput)
usage=load(usage);
figure();
if userInput==1
figure(1);
y=yearBuilt;
custom = 'v r';
z='Build Year';
else
figure(2);
if userInput == 2
y = yearReconstruct;
y(yearReconstruct==0)= NaN;
custom = '* b';
z='Reconstruction Year';
else
figure(3);
if userInput == 3
y=score;
custom ='. g';
z='Overall';
else
disp("Invalid input value, input must be either 1, 2, or 3");
end
end
end
hold on
x=names;
plot(y,custom,'Markersize',10,'lineWidth',2,'LineStyle','none');
xlabel('output');
ylabel(z);
grid on
set(gca,'xticklabel',x.')
xtickangle(-45);
end
My code keeps displaying empty graphs or multiple empty graphs.

You do not appear to have a variable yearBuilt. If this is part of your mat file, note that the syntax you use to load it loads it to a structure names usage.
Try using dot notation to access your variables.
y=usage.yearBuilt;
One comment about your plot inputs. These two settings do opposite things. You only need one or the other. LineStyle can also be set to 'none' by not specifying a style in the linespec input (your variable custom).
'lineWidth',2,'LineStyle','none'
