matlab调整legend大小,在Matlab Legend中更改符号大小

Matlab R2014a或更早版本

要增加字体大小：获取“text”类型的所有图例子项的句柄,并将其“Fontsize”属性设置为所需的值.

要增加标记大小：获取“line”类型的所有图例子项的句柄,并将其“Markersize”属性设置为所需的值.

plot(1:10, ‘o-‘);

hold on

plot(5:12, ‘r*–‘); %// example plots

h = legend(‘one plot’, ‘another plot’, ‘location’, ‘NorthWest’); %// example legend

ch = findobj(get(h,’children’), ‘type’, ‘text’); %// children of legend of type text

set(ch, ‘Fontsize’, 14); %// set value as desired

ch = findobj(get(h,’children’), ‘type’, ‘line’); %// children of legend of type line

set(ch, ‘Markersize’, 12); %// set value as desired

Matlab R2014b或更新版(HG2)

图例中元素的组织现在是不同的.以下作品：

plot(1:10, ‘o-‘);

hold on

plot(5:12, ‘r*–‘); %// example plots

[~, objh] = legend({‘one plot’, ‘another plot’}, ‘location’, ‘NorthWest’, ‘Fontsize’, 14);

%// set font size as desired

objhl = findobj(objh, ‘type’, ‘line’); %// objects of legend of type line

set(objhl, ‘Markersize’, 12); %// set marker size as desired
