Extracting spectral plot from HyperspectralViewer

Hi,
I'm quite a matlab rookie, and I was wondering how is it possible to extract spectral plot data for a single pixel in the HyperspectralViewer toolbox.
Ideally this would be extractable in plotable dataset.
Thanks,

Not possible from within the HyperspectralViewer app. However, you can achieve the same using the code below (just replace the spatial location row and column index with your intended ones).
% Read the hyperspectral image
hCube = hypercube("indian_pines.dat");
% Extract the DataCube adn wavelength
dataCube = hCube.DataCube;
wavelength = hCube.Wavelength;
% Extract the single spectral signature of the (50,50) spatial location
sig = dataCube(50,50,:);
sig = squeeze(sig);
% Plot the signature
figure
plot(wavelength,sig,"LineWidth",2)
axis tight
xlabel("Wavelength")
ylabel("Amplitude")
