To plot real-time data from the sensor in MATLAB, the animatedline function can be used to dynamically update the graph as new data is read. Below is an example of how to implement this (using random values for acceleration):
figure;
hold on;
grid on;
title('Simulated Real-Time Acceleration Data');
xlabel('Time (s)');
ylabel('Acceleration (m/s^2)');
hX = animatedline('Color', 'r', 'DisplayName', 'X');
hY = animatedline('Color', 'g', 'DisplayName', 'Y');
hZ = animatedline('Color', 'b', 'DisplayName', 'Z');
legend;
startTime = datetime('now');
for i = 1:100
accelReadings = readAcceleration();
t = datetime('now') - startTime;
t = seconds(t);
addpoints(hX, t, accelReadings.X);
addpoints(hY, t, accelReadings.Y);
addpoints(hZ, t, accelReadings.Z);
drawnow;
pause(0.1);
end
function accel = readAcceleration()
accel.X = 2 * rand() - 1;
accel.Y = 2 * rand() + 1;
accel.Z = 2 * rand() + 3;
end
For more information on animatedLine, refer to the following documentation:
Hope this helps measure and plot as and when data is available.
