Yeah, you're going to have problems trying to create a bunch of line objects for all the segments. You'll probably have a better time doing it with patch() and using a color table.
% a cell array of floating-point integer vectors
logic_outputs = {[1 2 3 2 1 3 2 2 2 1], [3 1 1 1 3 3 3 1 1 1],[2 1 3 2 3 2 3 1 1 1]};
% the color table
CT = [0 1 0; 1 1 0; 1 0 0; 0 0 0];
% sizes of things
num_lines = numel(logic_outputs);
num_verts = numel(logic_outputs{1})+1; % assuming they're the same length
% Create a time vector
time_vector = linspace(0, 1600, num_verts);
% Set the heights for each line
line_heights = [568, 780, 1500];
% use patch() to create three colored lines
hold on
for k = 1:numel(logic_outputs)
patch([time_vector NaN], ...
[repmat(line_heights(k),[1 num_verts]) NaN], ...
[logic_outputs{k}([1:end end]) NaN], ...
'EdgeColor','flat','LineWidth',5,'cdatamapping','direct');
end
colormap(CT)
% Set axis limits and labels
xlim([0 1600]);
xlabel('Time (seconds)');
ylabel('Segment Status');
The third argument to patch() is the color data, given here as a vector of indices into the rows of CT. This index vector is expected to be integer-valued, but it's also class-sensitive. If the contents of logic_outputs are float class (e.g. 'double'), then indexing starts at 1, like everything else in MATLAB. If those vectors are instead integer-class (e.g. uint8), then indexing starts at 0 instead.
