title：向图中添加标题
示例：
clc;clear;% 绘制x = linspace(0,2*pi);y = sin(x) - tan(sin(x));plot(x,y)title('y = sin(x)-tan(sin(x))')
结果展示：
2 添加轴标签
xlabel：x轴标签
ylabel：y轴标签
zlabel：z轴标签（plot3）
示例：
clc;clear;% 绘制x = linspace(0,2*pi);y = sin(x)-tan(sin(x));plot(x,y)title('y = sin(x) - tan(sin(x))')xlabel('X(m)')ylabel('Y(m)')
结果展示：
3 添加图例
legend：按绘图顺序添加图例
示例：
clc;clear;% 绘制x = linspace(0,2*pi);y = sin(x)-tan(cos(x));plot(x,sin(x))hold onplot(x,cos(x))hold onplot(x,tan(cos(x)))hold onplot(x,y)hold offtitle('添加图例')xlabel('X(m)')ylabel('Y(m)')% 按绘图顺序添加图例legend('y = sin(x)','y = cos(x)','y = tan((cos(x))','y = sin(x) - tan(cos(x))')
结果展示：
4 更改标题、标签、图例的字体大小
'FontSize'字号属性
示例：
clc;clear;% 绘制x = linspace(0,2*pi);y = sin(x)-tan(cos(x));plot(x,sin(x))hold onplot(x,cos(x))hold onplot(x,tan(cos(x)))hold onplot(x,y)hold offtitle('添加图例','FontSize',20)xlabel('X/(m)','FontSize',15)ylabel('Y/(m)','FontSize',10)% 按绘图顺序添加图例legend('y = sin(x)','y = cos(x)','y = tan((cos(x))','y = sin(x) - tan(cos(x))')
结果展示：
