Plot time on x axis for 24 hours duration

How can i plot my data against time on x axis which is 24 hours duration split every two hours.

Sample has been attached here.

Hi NN,

To plot your data against time on the x-axis over a 24-hour duration, split every two hours, you can use MATLAB's datetime and plotting functions to handle time formatting and axis labeling.

The below code demonstrates how to achieve this using dummy data, along with explanatory comments:

% Sample data
data = rand(1, 13); % Replace with your actual data

% Create a time vector for 24 hours split every two hours
startTime = datetime('today', 'Format', 'HH:mm');
endTime = startTime + hours(24);
timeVector = startTime:hours(2):endTime;

% Ensure the data length matches the time vector length
if length(data) ~= length(timeVector)
    error('Data length must match the number of time points.');
end

% Plot the data
figure;
plot(timeVector, data, '-o');
title('Data over 24 Hours');
xlabel('Time');
ylabel('Data Value');
grid on;

% Format the x-axis
ax = gca;
ax.XTick = timeVector; % Set x-ticks to the time vector
ax.XTickLabelRotation = 45; % Rotate x-tick labels for better readability
ax.XLim = [startTime, endTime]; % Set x-limits to the start and end time

For more details, please refer to the following MathWorks documentation: Represent Dates and Times in MATLAB- https://www.mathworks.com/help/matlab/matlab_prog/represent-date-and-times-in-MATLAB.html

Hope this helps!
