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');

- This code keeps on generating graphs with different curves. The picture that you see two different graphs comes from the same code but both of them have different curves. I need the curve to look like the picture that only has one graph. I basically need the line to have a slight curve and every time I run the code it will come up as the same graph every time.
