基本數(shù)據(jù):
data = rand(25)+repmat(1:25,25,1); H = plot(data);
基本用法:
legend({'str1','str2','strn'});
高級用法1:指定legend顯示的位置:
legend({'str1','str2','strn'},1);
legend({'str1','str2','strn'},2);
legend({'str1','str2','strn'},'Location','SouthEast');
可選的位置很多:
North:Inside plot box near top South:Inside bottom EastI:nside right West:Inside left NorthEast:Inside top right (default) NorthWest:Inside top left SouthEast:Inside bottom right SouthWest:Inside bottom left NorthOutside:Outside plot box near top SouthOutside:Outside bottom EastOutside:Outsideright WestOutside:Outside left NorthEastOutside:Outside top right NorthWestOutside:Outside top left SouthEastOutside:Outside bottom right SouthWestOutside:Outside bottom left Best:Least conflict with data in plot BestOutside:Least unused space outside plot
通常,,用'Best‘比較不錯
高級用法2:指定顯示某幾條曲線的legend:
方法1:復(fù)雜到吐血
例如你有25條曲線,想顯示其中1,,6,,11,16,,21的legend,,則
for i = [2:5 7:10 12:15 17:20 22:25] set(get(get(H(i),'Annotation'),'LegendInformation'),'IconDisplayStyle','off'); end legend('1','6','11','16','21');
方法2:簡單到郁悶
H = plot(data); legend(H([1 6 11 16 21],'1,'6','11’,'16','21');
高級用法3:legend橫排
hl = legend(H([1 6 11 16 21],'1,'6','11’,'16','21'); set(hl,'Orientation','horizon')
高級用法4:不顯示方框:
hl = legend(H([1 6 11 16 21],'1,'6','11’,'16','21'); set(hl,'Box','off');
