Plot vectors in cell array over for loop

I have the following data structure (a cell array populated with vectors):

sigvecarray = {};
freqarray = {};

% Reading the audio files, getting the signal vector and the corresponding 
for k = 1:numel(inputarray) % indices
    curr_input = inputarray{k};
    [y, Fs] = audioread(curr_input);
    sigvecarray{k} = y;
    freqarray{k} = Fs;
end

I'm trying to plot them over a for loop by using the following:

for k = 1:numel(sigvecarray)
    plot(sigvecarray{k})
end

But I get only the fist vector plotted as my output. What could I be doing wrong here? Is it because the cell array is a row vector? If yes, how do I convert the cell array to a column vector from a row vector?

hold on
for k = 1:numel(sigvecarray)
    plot(sigvecarray{k})
end
