I have a 1000x501 table in which the 1st column is wavelength and the rest are the run number when I do the experiment. How can I plot it as the example below? I want the x is wavelength, y is run number and color for the value of y. Thanks~

Let A be your table.
wavelength = A(:,1) ;
Time = 1:size(A,2)-1 ;
data = A(:,2:end) ;
h = pcolor(wavelength,Time,data') ;
h.EdgeColor = 'none' ;
xlabel('Wave length')
ylabel('Time')
Also have a look on heatmap
