Plot time-series data

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')
