How do i compare graphs ( plots ).

How can i compare the graph ( plots ) like area & stacked bar plots. Is there any option to find out the similarity between them?

Hi @Mitesh Bhavsar,

Although visual inspection is the most straightforward way to compare the plots, but you can try the following methods to find the similarity in your plots:

Numerical comparison:

Calculate the correlation coefficient to measure similarity.

% Example data 
x = 1:10; 
y1 = rand(1, 10); % Data for area plot 
y2 = rand(1, 10); % Data for stacked bar plot 
correlation = corrcoef(y1, y2); 
disp(['Correlation between datasets: ', num2str(correlation(1,2))]);

Overlay Plots:

figure; 
hold on; 
area(x, y1, 'FaceAlpha', 0.5, 'FaceColor', 'r'); 
bar(x, y2, 'stacked', 'FaceAlpha', 0.5, 'FaceColor', 'b'); 
title('Overlay of Area and Stacked Bar Plot'); 
legend('Area Plot', 'Stacked Bar Plot'); 
hold off; 

Statistical Analysis:

% Compute Mean Squared Error 
mse = mean((y1 - y2).^2); 
disp(['Mean Squared Error between datasets: ', num2str(mse)]); 

Hope it helps!
