Question

I’m using this code in MATLAB but for some odd reason every time I run it on MATLAB I keep on getting a different graphs. In the picture that shows two different graphs are from the same code, but I need to it to look like the picture that has one graph. Could you please fix it. To make it look like the picture that has one graph? Here is the code: % Sample data for Diesel and Petrol carPosition = linspace(1, 60, 50); % Assumed positions of cars CO2Diesel = 25 + 5*cos(carPosition/60*2*pi) + randn(1, 50)*5; % Random data for Diesel CO2Petrol = 20 + 5*sin(carPosition/60*2*pi) + randn(1, 50)*5; % Random data for Petrol % Fit polynomial curves pDiesel = polyfit(carPosition, CO2Diesel, 3); pPetrol = polyfit(carPosition, CO2Petrol, 3); % Generate points for best fit lines fitDiesel = polyval(pDiesel, carPosition); fitPetrol = polyval(pPetrol, carPosition); % Plotting the data figure; hold on; scatter(carPosition, CO2Diesel, 'o', 'MarkerEdgeColor', [1 0.5 0]); % Diesel data scatter(carPosition, CO2Petrol, 'o', 'MarkerEdgeColor', [0 0.5 1]); % Petrol data plot(carPosition, fitDiesel, 'Color', [1 0.5 0], 'LineWidth', 2); % Diesel best fit plot(carPosition, fitPetrol, 'Color', [0 0.5 1], 'LineWidth', 2); % Petrol best fit % Customize the plot xlabel('Car Position'); ylabel('CO2 Weighted Percentage'); title('Weighted CO2 Emissions'); legend('Diesel', 'Petrol', 'Diesel Best Fit', 'Petrol Best Fit'); grid on; hold off;
