Hi Kishor,
From my understanding, you are reading the data from a sensor and capturing it into a CSV file. You want to plot the data continuously from the CSV file in real time.
To achieve this, we can first set up the MATLAB environment by defining the CSV file path and figure. Now, we can iterate over a loop to continuously read the data from the CSV file using “readmatrix” function and plot it using the “plot” function in MATLAB. As the size of CSV file continues to increase over time, updated plots will get generated in real time.
Here is the MATLAB code to accomplish this task:
% Define the file path
filePath = 'your_sensor_data.csv';
figure;
while true
% Read the CSV file
data = readmatrix(filePath);
% Assuming the data has two columns, time and sensor value
time = data(:, 1);
sensorValue = data(:, 2);
plot(time, sensorValue);
xlabel('Time');
ylabel('Sensor Value');
title('Real-Time Sensor Data');
grid on;
% Pause for a short time to allow the plot to update
pause(1);
% Clear the plot for the next update
clf;
end
Please find attached the documentation of functions used for reference:
I hope you found the information insightful.
