Hi Hongyun,
To answer your question,
Import the PNG map using imread function.
% Import the PNG map
map = imread('your_map.png');
Display the map using imshow.
% Display the map
imshow(map);
hold on;
Plot the bar chart on top of the map using bar function.
% Define data for the bar chart
data = [10, 20, 15, 25];
% Plot the bar chart on the map
bar(data);
Adjust the bar chart properties like color, width, and spacing to enhance visualization.
% Customize bar chart properties title('Bar Chart on Map'); xlabel('Categories'); ylabel('Values'); legend('Data');
If you follow these steps, you can seamlessly integrate bar charts with maps in MATLAB for effective data visualization. Please let me know if you have any further questions.
