My script is not giving me the title, xlabel, and ylabel that I am asking so how can I fix it?

function [xy]= plotData(filename,markers)
%data=xlsread('data.xlsx');
[num,txt]=xlsread(filename);
x=num(:,1);
y=num(:,2);
title(filename)
xlabel(txt{1})
ylabel(txt{2})
if markers==true
plot(x,y,'k-o');
else
plot(x,y,'k-');
end

upload your file and what is markers? provide its data too

Michael - this looks like very similar code to the homework assignment found at https://www.mathworks.com/matlabcentral/answers/431909-for-an-assignment-i-need-to-create-a-function-that-creates-a-graph-using-data-from-an-imported-excel. Try stepping through the code with the MATLAB debugger to trouble-shoot what is going wrong.

Call title, xlabel, and ylabel after calling plot. By default calling plot is going to clear graphics objects from the axes, reset most axes properties to their default values, and calculate new axes limits as stated on this documentation page.
