How do I set up a legend like this(two curves one legend then some gap)??![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/1604281/image.png)

The plots you show have custom legends.
Try this link available in FEX where you can change the legend layout and behavior as you wanted

Why not plot an empty line along side and use a blank as its legend entry?
x = 0:0.01:10;
figure
plot(x, sin(x))
hold on
plot(x,cos(x));
plot(x,floor(x/5))
plot(x,NaN(size(x)))
xlim([-1 11])
str = ["sin" "cos" "custom" ""];
legend(str, 'NumColumns', 2)

Set the original legend to 'Location','NE' and then use:
legend('boxoff')

Hello Shahriar,
It looks like you want to overlay two sets of axes, with the larger one encompassing the smaller, and include a common legend for both in MATLAB. To accomplish this task, adhere to the following instructions:
- First, Create an axes called "larger" and add plots to it.
- Next, define a another axes called "smaller" to be positioned within the "larger" axes.
- Finally,to create a common legend, plot invisible lines and assign the legends to them.
Here's the MATLAB code for your reference:
x = linspace(1, 10, 100);
y1 = log(x);
y2 = log(x.^2);
y3 = log(x.^3);
y4 = log(x.^4);
figure;
larger = axes;
plot(larger, x, y1, 'r-', x, y2, 'b-', x, y3, 'g-', x, y4, 'k-');
hold(larger, 'on');
smaller = axes('Position', [0.2 0.6 0.25 0.25]);
plot(smaller, x, y1, 'r-', x, y2, 'b-', x, y3, 'g-', x, y4, 'k-');
h1 = plot(larger, NaN, NaN, 'r-');
h2 = plot(larger, NaN, NaN, 'b-');
h3 = plot(larger, NaN, NaN, 'g-');
h4 = plot(larger, NaN, NaN, 'k-');
legend(larger, [h1, h2, h3, h4], {'log(x)', 'log(x^2)', 'log(x^3)', 'log(x^4)'});
Hope this helps you to understand how to have a common legend for two nested axes
