How do you I get my program to label the axes using the column headings in my excel file?

I have three column headers in an excel file: A1:A1 is time, B1:B1 is velocity. This is what I have so far but I cant get my plot to label the axes. Please help me out .

clear;
clc;

data = xlsread('veldata.xlsx');
t = data(:,1);
v1 = data(:,2);
v2 = data(:,3);
avg_v1v2 = ((v1 + v2)/2);
plot(t,v1,'b',t,v2,'g',t,avg_v1v2,'r:')
xlabel(xlsread('veldata.xlsx','Sheet1','A1:A1'))

[data, txt, raw] = xlsread('veldata.xlsx');
% other code...
col1Header = txt{1, 1};
col2Header = txt{1, 2};
xlabel(col1Header, 'FontSize', 25);
ylabel(col2Header, 'FontSize', 25);

Adapt as needed.
