matrix - Matlab - plot and color samples based on data -

i have following data:

i plot data in normal way:

plot(wavelength, datamatrix)

but want plot , color each sample according concentration value taking account rest, color based on data. think colormap. result this:

is there easy way using matlab?

thank much!

plot accepts line property including line color,

plot(wavelength, datamatrix, 'color', [0,0,0.1])

colormap can convert built-in color maps rgb matrices,

nlines = length(concentrations); cmap = hsv(nlines)

mapping concentration color easy sorting numbers

c = concentrations - min(concentrations); c = ceil( c/max(c)*nlines );

finally, draw each line separately

for ii = 1:nlines     plot(wavelength, datamatrix(ii,:), 'color', cmap(c(ii),:))     hold on end hold off
