NorthEastOutside：Outside top right

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]

set(get(get(H(i),'Annotation'),'LegendInformation'),'IconDisplayStyle','off');

end

legend('1','6','11','16','21');

方法2：简单到郁闷

H = plot(data);

legend(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');

set(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');

set(hl,'Box','off');

另外，去掉legend边框，可以参考：

legend('x','y')

legend('boxoff')

写两次就好了。matlablegendmatlablegend我最初尝试着写成legend('x','y','boxoff')是不行的。

修改legend的字体：

legend1=legend('x','y');

set(legend1,'FontName','Times NewRoman','FontSize',12,'FontWeight','normal');

修改legend位置：

i=0;%i=0，自动调整最佳位置；i=1，右上；i=2，左上；i=3，左下；i=4，右下；

legend1=legend('x','y'，i);

最好的说明文档，当然是帮助文档：

matlab:

doc legend

legend('hide'), legend(axes_handle,'hide') makes the legend in thecurrent axes or the axes specified by axes_handle invisible.
