I can gnerate the reflectance for different wavelength and diameter. In excel it ends up as a table, where the top row is assigned for diameter, and the leftmost column is assigned for wavelength. The remaining cell values are the reflectance at a particular wavelength and particular diameter. I need to plot like the following figure. Please share the code

data = readmatrix(xlsfileName);
imshow(data, [], 'XData', [0, 500], 'YData', [300, 1200]);
xlabel('D (nm)')
colormap(jet(256));
colorbar;
Then use text() function to overlay the words.

I recommend using the row and column headers. Then those can be pulled out of the data as the first row and column
data = readmatrix(xlsxFileName);
diameters = data(1, 2:end);
wavelengths = data(2:end, 1);
signal = data(2:end, 2:end);

I recommend looking at the MATLAB Plot Gallery, finding a figure that is close to what you need, and pulling the code from there.
