how can I display the sensor data, altitude, speed, flight control on a graph ?

close all;

clc; clear;

r = ryze();

takeoff(r);

fig2 = figure('pos',[800 550 800 450]);

subplot(2,3,1)

title('phi[deg]');

grid on;

hold on;

subplot(2,3,2)

title('theta[deg]');

grid on;

hold on;

subplot(2,3,3)

title('psi[deg]');

grid on;

hold on;

subplot(2,3,4)

title('x[m]');

grid on;

hold on;

subplot(2,3,5)

title('y[m]');

grid on;

hold on;

subplot(2,3,6)

title('zdot[m/s]');

grid on;

hold on;

% function extractSensorData(obj, sensorData)

% Function to extract individual sensor data from the packet

% containing all drone sensor data

% Update battery level

obj.BatteryLevel = str2double(extractBetween(sensorData,'bat:',';'));

if(obj.BatteryLevel < 10)

status = ryzeio.internal.Utility.validateAlertState(obj.LowBattery, obj.BatteryLevel);

% Set the low battery flag

if(status)

obj.LowBattery = true;

end

end

% Update Attitude/Orientation Values

Pitch = str2double(extractBetween(sensorData,'pitch:',';'));

Roll = str2double(extractBetween(sensorData,'roll:',';'));

Yaw = str2double(extractBetween(sensorData,'yaw:',';'));

obj.Attitude.Value = [Yaw Pitch Roll];

obj.Attitude.Time = datetime('now', 'TImeZone','local','Format','dd-MMM-uuuu HH:mm:ss.SS');

% Update the Altitude/height of the drone

obj.Altitude.Value = str2double(extractBetween(sensorData,';h:',';'));

obj.Altitude.Time = datetime('now', 'TImeZone','local','Format','dd-MMM-uuuu HH:mm:ss.SS');

% Update the speed of the drone

vgx = str2double(extractBetween(sensorData,'vgx:',';'));

vgy = str2double(extractBetween(sensorData,'vgy:',';'));

vgz = str2double(extractBetween(sensorData,'vgz:',';'));

obj.Speed.Value = [vgx vgy vgz];

obj.Speed.Time = datetime('now', 'TImeZone','local','Format','dd-MMM-uuuu HH:mm:ss.SS');

if(~obj.FirstPacketReceived)

% Make the 'FirstPacketReceived' true to indicate

% that the first packet of sensor data has arrived

obj.FirstPacketReceived = true;

end

The following example explains in detail how to plot the ryze tello drone's flight data https://www.mathworks.com/help/supportpkg/ryzeio/ug/read-plot-navigation-data-using-matlab-support-package-for-ryze-tello-drones.html

It plots data such as speed, orientation, and height against time.
