使用[l，icons，plots，txt] = legend（）时，Matlab图例字体大小不会更新

标签： matlab plot matlab-figure legend legend-properties

我很难更改Matlab R2016a中绘图图例中使用的字体大小。如果我使用首选语法l = legend（），那么它可以正常工作。但是，我需要访问图标句柄才能更改facea属性。因此，我使用的语法[l，icons，plots，txt] = legend（）根据Matlab＆＃34;不建议创建一个不支持所有图形功能的图例。＆＃34;使用此语法时，字体大小无法正确更新。反正有没有获得正确的字体大小和透明的图例图标？

%% Some data to plot
x=linspace(1,10);
y=linspace(1,20);
[xx,yy]=meshgrid(x,y);
zz1=2*xx+3*xx.*yy+yy.^2;

%% Correct font, but icons not transparent
figure(1)
h=surf(x,y,zz1,'FaceColor','b','EdgeColor','none');
alpha(h,0.4)
l=legend('plot1');
l.FontSize=24;
l.FontName='Wide Latin';

%% Icons transparent, but incorrect font
figure(2)
h=surf(x,y,zz1,'FaceColor','b','EdgeColor','none');
alpha(h,0.4)
[l,icons,plot,text]=legend('plot1');
l.FontSize=24;
l.FontName='Wide Latin';
set(findobj(icons,'type','patch'),'facea',0.4)

在多输出调用中，看起来字体大小附加到Legend的第二个输出。试试这个例子：

直接适用于您的代码：

%Plot some data and a legend
[X,Y,Z] = peaks;
surf(X,Y,Z)
[LEGH,OBJH,OUTH,OUTM] = legend('Peaks legend');

%Change the transparency of the legend patches
OBJH(2).FaceAlpha = 0.4;  %Your "findobj" call is probably more reliable.

%Change the fontsize
OBJH(1).FontSize = 6;   %Your "findobj" call is probably more reliable.

%If you change the "fontsize" of the main legend object, 
%    that seems to change the size of the legend box, but not the contents.
LEGH.FontSize = 16;
%This could actually be useful, for example to fine tune the size 
%    of the box. But it is pretty counterintuitive.

（我目前正在运行R2015a。在更新版本中，这种精细的详细行为可能会略有改变。）

有同样的问题 - 我可以通过单步执行或从命令行运行图标（ii）.FontSize，但不会在脚本中响应。
我在循环之前添加了一个暂停（0.1），瞧！
