Hello I’m trying to make the graph that you see in the picture but I am having trouble on make the two lines that you see on the graph to over lap each other, I don’t want the two lines to be separate I want the two lines on top of eachother like you see in the picture please fix the code so that the Diesel line is on top of the Petrol line as seen on the picture. % Sample data for Diesel and Petrol cars carPosition = linspace(1, 60, 50); % Assumed positions of cars % Fix the random seed for reproducibility rng(45); % 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; % Diesel data scatter(carPosition, CO2Diesel, 'o', 'MarkerEdgeColor', [1 0.5 0]); % Petrol data scatter(carPosition, CO2Petrol, 'o', 'MarkerEdgeColor', [0 0.5 1]); % Diesel best fit plot(carPosition, fitDiesel, 'Color', [1 0.5 0], 'LineWidth', 2); % Petrol best fit plot(carPosition, fitPetrol, 'Color', [0 0.5 1], 'LineWidth', 2); % 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; % Adjust axis limits to match the provided image xlim([1 60]); ylim([15 35]); hold off;
