hidelegend

FYI, please see the attached figure.

My aim is to hide or delete the legend data1, data2 and data3, to be like this figure.

Thanks!

Use line objects as inputs to legend, telling it which lines to include in the legend.

x=1:10;
y=@(x,a)((x-5)/a).^2;
p1 = plot(x,y(x,1),'DisplayName','Mode 1,Analytical,UD');
hold on
plot(x,y(x,1.1));
p2 = plot(x,y(x,2),'DisplayName','Mode 2,Analytical,UD');
plot(x,y(x,2.2));
p3 = plot(x,y(x,3),'DisplayName','Mode 3,Analytical,UD');
plot(x,y(x,3.3))
hold off
legend([p1,p2,p3])

MATLAB: Change the lines’ widths in a stem plot, without changing the markers edges widths

You will need to use a combination of stem and scatter to get such a result. Check the following code

x = 1:10;
y = rand(1,10);
subplot(3,1,1)
stem(x,y,'LineWidth',2,'MarkerSize',15,'MarkerFaceColor','g')
subplot(3,1,2)
stem(x,y,'LineWidth',2,'MarkerSize',15,'MarkerFaceColor','g', 'MarkerEdgeColor', 'none')
subplot(3,1,3)
hold on
stem(x, y, 'LineWidth', 2, 'Marker', 'none')
scatter(x, y, 'filled', 'MarkerEdgeColor', 'b', 'MarkerFaceColor', 'g', 'SizeData', 200, 'LineWidth', 0.5)
