plot ''markers'' in graph

Hi everybody,

I have a time vector and a data vector. Furthermore I have a vector with specific time points that indicated the start of a wave. I would like to plot them together to see if the start of the wave time is correct. At the moment I can't plot them together because of the fact that the vectors are not of the same length and furthermore plotting the specific time points wil give a line while I would like to have 'markers' or points. Can somebody help?

If understood your question correctly, this is what you are trying to do:

t = 0:.1:3;             % Time  
Data = exp(2*cos(t));        % Data vector 

rng(1)                  % For this demo reproducibility purposes

ts = rand(1);           % Wave starts at a time point 
dt = 0.05;              % Wave collected at a time step
tend = 5*rand(1);       % Wave data collection ends at this time
tpoints = ts:dt:tend;   % Specific time points at which the wave data was collected
Wave = sin(2*tpoints);    % Wave Data vector
plot(t, Data, 'r--', 'DisplayName', 'Data with time')
hold on
plot(tpoints, Wave, 'bo-.', 'DisplayName', 'Wave with specific time points')
legend('Show')
xlabel('Time, [s]')
ylabel('Data & Wave')
grid on
