Question
I need help with the purple line the line that you see one the graph on the picture needs to be on the graph.
Use this code to add the purple line and make sure it’s crossing the orange line. Please make sure the lines are positioned the same way it is shown on the picture with the graph.
Use this code on MATLAB and add the purple line.
% Sample data for Diesel and Petrol cars
carPosition = linspace(1, 60, 50); % Assumed positions of cars
% Use the 'seed' function instead of 'rng'
seed = 50; % Define your seed here
rand('seed',seed);
% Assumed CO2 emissions for Diesel and Petrol
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 with a reduced degree of 2
pDiesel = polyfit(carPosition, CO2Diesel, 2);
pPetrol = polyfit(carPosition, CO2Petrol, 2);
% Generate points for best fit lines
fitDiesel = polyval(pDiesel, carPosition);
fitPetrol = polyval(pPetrol, carPosition);
% Combined best fit
combinedFit = (fitDiesel + fitPetrol) / 2;
% Plotting the data
figure; hold on;
% Define the split index and shorten the purple line
splitIndex = round(length(carPosition) / 2);
shortenIndex = round(length(carPosition) * 0.8);
% Plot the combined best fit line (connect orange and purple, purple line shorter)
plot(carPosition(1:shortenIndex), combinedFit(1:shortenIndex), 'Color', [1, 0.5, 0], 'LineWidth', 2); % Orange to shorter purple
plot(carPosition(shortenIndex:end), combinedFit(shortenIndex:end), 'Color', [0.5, 0, 1], 'LineWidth', 2); % Shortened Purple
% Petrol data
scatter(carPosition, CO2Petrol, 'o', 'MarkerEdgeColor', [0 0.5 1]); % Blue for Petrol
% Diesel data
scatter(carPosition, CO2Diesel, 'o', 'MarkerEdgeColor', [1 0.5 0]); % Orange for Diesel
% Customize the plot
xlabel('Car Position');
ylabel('CO2 Weighted Percentage');
title('Weighted CO2 Emissions');
% Adjust axis limits
xlim([1 60]);
ylim([15 35]);
% Add a legend with custom names
legend('Diesel Best Fit', 'Petrol Best Fit', 'Petrol', 'Diesel');
% Add grid lines
grid on; hold off;
