plot many channels with same x axis and repeated y axis values
显示 更早的评论
Hello Everyone,
I would like to know which method could be the best in order to get an image like the one in the attachments
it represent a linear probe that goes deep into the brain surface, whith 16 channels in Y axis. As you could see, each channels displays different values, but they share the same x-y axis range.
i have a matrix with 2000 time points filled with values x 16 channels. I would like to get an image close to the one displayed, plus the function should make easy to change the range of channels displayed (16 now and then 5 channels only)
Thanks so much in advance

You can also use stackedplot function given in following link
for similar output

X = rand(20, 200); % Some test data
XX = X + (0:19).'; % Shift vertically
plot(1:200, XX)

permute(X, [2,1]) can be simplified to X.' , because this is transposing.
Maybe your data have to be scaled:
Y = new_ch(:, 1:32).';
Y = Y ./ max(abs(Y), [], 1); % Divide by maximum value
% Then all values are between -1 and 1
Y = Y + (1:32).';
plot(1:width(Y), Y);

X = rand(20, 200); % Some test data
XX = X + (0:19).'; % Shift vertically
plot(1:200, XX);
YL = get(gca, 'YLim');
T = rand(1, 20) * 200; % Some time points
line([T; T], YL, 'LineStyle', ':', 'Color', 'k', ...
'LineWidth', 1.5);
