It is my understanding that you are trying to plot a “stem3” graph using data from a file that has multiple sequences of data. If this is the needed requirement, you may read the data into a variable, and then use it to plot a “stem3” graph. Additionally, you can then use the “hold on” command to plot each entry using a loop as per your use case on to the same plot.
Please feel free to refer to the documentation page linked below.
Here is a sample code for your reference.
x = randi(9, 2, 5); % Create Data
y = randi(9, 2, 5); % Create Data
z = randi(9, 2, 5); % Create Data
axis([0 10 0 10 0 10]) % The ‘axis’ Call Must Be Placed Here
figure(1)
hold on
for i=1:2
stem3(x(i,:), y(i,:), z(i,:))
end
hold off
