You may use readtable, readmatrix, or readcell function to read the excel sheet.

plot(readMatrixOutput(:,2)) % Using second column of matrix as it has temperature values

% Change the labels of x-axis
xticklabels({'Day 1 (January 3)','Day 2 (January 4)','Day 3 (January 5)'})

Refer this link for documentation of xticklabels.

I wanted to generate labels such as "Day 1 (January 3)" using Matlab not manually.

You may try datetick function. I am not sure of Day 1 (January 3) format, but you can generate January 3 format automatically
