Hi Morteza,
I understand that you want to create a legend in a MATLAB plot that is displayed in two columns, with the first column containing four items and the second column containing three items.
You can use the "legend" function to create a legend with multiple columns. Set the "NumColumns" property to 2 to split the legend into two columns. This creates a legend with first column and second column containing 4 and 3 columns respectively.
Here is the sample code that demonstrates the same:
% Example data
x = 1:10;
y1 = rand(1, 10);
y2 = rand(1, 10);
y3 = rand(1, 10);
y4 = rand(1, 10);
y5 = rand(1, 10);
y6 = rand(1, 10);
y7 = rand(1, 10);
% Plot data
figure; % Create a new figure
plot(x, y1, '-o', 'DisplayName', 'Data 1'); hold on;
plot(x, y2, '-s', 'DisplayName', 'Data 2');
plot(x, y3, '-^', 'DisplayName', 'Data 3');
plot(x, y4, '-d', 'DisplayName', 'Data 4');
plot(x, y5, '-x', 'DisplayName', 'Data 5');
plot(x, y6, '-+', 'DisplayName', 'Data 6');
plot(x, y7, '-*', 'DisplayName', 'Data 7');
hold off;
% Create a two-column legend
lgd = legend('NumColumns', 2);
% Add title and labels
title('Example Plot with Multi-Column Legend');
xlabel('X-axis');
ylabel('Y-axis');
% Display grid
grid on;
Output with legend having 2 columns:
Refer to the documentation of "legend" for customizing legends: https://www.mathworks.com/help/matlab/ref/legend.html
I hope this helps!
