标题: Matlab绘图中legend的终极用法

基本用法：

legend({'str1','str2','strn'});

高级用法1：指定legend显示的位置：

legend({'str1','str2','strn'},1);

legend({'str1','str2','strn'},2);

legend({'str1','str2','strn'},'Location','SouthEast');

可选的位置很多：

North：Inside plot box near top
+ w  E' M! C; u& f* ^South：Inside bottom
& w' c7 a% ~* a, Q- }1 a" O8 FEastI：nside right
& Y8 x/ h' ?6 E- Q. Y& g" Q$ I5 @West：Inside left* U$ D" a* Q/ Y: }- I: v: [
NorthEast：Inside top right (default)2 i/ U; O: d* S. v3 G) K" S
NorthWest：Inside top left( X! A1 U' W: V7 U8 {: s& |
SouthEast：Inside bottom right0 U" X. X. i; V; Q. G0 s
SouthWest：Inside bottom left' ^! L3 J5 V) e7 z4 v
NorthOutside：Outside plot box near top2 [9 c3 P( y, `) j: N* J. r
SouthOutside：Outside bottom
# B. x+ x( W$ gEastOutside：Outsideright
7 [" ~. b3 J, M1 K1 `WestOutside：Outside left: C% S" n! b" F7 c- A2 ~5 K( |7 f
NorthEastOutside：Outside top right
; q2 x( _2 g  C( INorthWestOutside：Outside top left
# k& J( {# u! G9 w; |SouthEastOutside：Outside bottom right6 G  {9 P6 P2 I; L. ?
SouthWestOutside：Outside bottom left
1 L& U/ u  ~/ ?1 T$ J. ABest：Least conflict with data in plot
' j/ I& `+ r+ o' d6 ZBestOutside：Least unused space outside plot

通常，用'Best‘比较不错

高级用法2：指定显示某几条曲线的legend：

方法1：复杂到吐血

例如你有25条曲线，想显示其中1，6，11，16，21的legend，则

for i = [2:5 7:10 12:15 17:20 22:25]
' M/ C1 r7 E# ]" X- z9 ]set(get(get(H(i),'Annotation'),'LegendInformation'),'IconDisplayStyle','off');6 }8 [& f3 a1 e3 W+ d0 D
end
" m) k/ n7 v2 Y% D! A# Slegend('1','6','11','16','21');

方法2：简单到郁闷

H = plot(data);
2 w/ W* G9 Y9 U4 Ilegend(H([1 6 11 16 21],'1,'6','11’,'16','21');

高级用法3：legend横排

hl = legend(H([1 6 11 16 21],'1,'6','11’,'16','21');
3 P* F. E7 I. mset(hl,'Orientation','horizon')

高级用法4：不显示方框：

hl = legend(H([1 6 11 16 21],'1,'6','11’,'16','21');* A" q* {; d+ V" N0 Z
set(hl,'Box','off');
