multi columns legend in Matlab plots

Hello everyone

How can I have my legend in two columns with specific numbers in each columns?

for example I have 7 different datas in one plot and I want to have my legend in two columns so that there are 4 datas in first column and 4 datas in second column.

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:

I hope this helps!
