MATLAB绘图入门庖丁解牛 - 图例位置和风格修改-Self-disciplined,Self-Motivated

设置图例位置

默认位置是NorthEast 除了可以更改图例东西南北（图框的上下左右侧）位置，还可以设置图例显示在图片之外

clc
clear 
close all
Npoint = 101;
x = linspace(0,10,Npoint);
y1 = besselj(1,x);
y2 = besselj(2,x);
y3 = besselj(3,x);
y4 = besselj(4,x);
y5 = besselj(5,x);
H = plot(x,y1,x,y2,x,y3,x,y4,x,y5);
legend('First','Second','Third','Fourth','Fifth','Location','NorthEastOutside')

横向排列图例

%Matlab中legend的横排，注意，Location位置改变为North

Npoint = 101;
x = linspace(0,10,Npoint);
y1 = besselj(1,x);
y2 = besselj(2,x);
y3 = besselj(3,x);
y4 = besselj(4,x);
y5 = besselj(5,x);
H = plot(x,y1,x,y2,x,y3,x,y4,x,y5);
h1 = legend(H([1 3 5]),'First','Third','Fifthth','Location','North');
set(h1,'Orientation','horizon')
% set(h1,'Orientation','horizon','Box','off')；%不显示图例方框
