1、备注在coloebar上方

c1=colorbar;

set(get(c1,'title'),'ssh(cm)','fontsize',20);

2、备注在colorbar侧面

c1=colorbar;

set(get(c1,'ylabel'),'string','sea level trend(mm/year)','fontsize',20);

x1 = linspace(0,5);
y1 = sin(x1/2);
plot(x1,y1)

hold on
x2 = [0 1 2 3 4 5];
y2 = [0.2 0.3 0.6 1 0.7 0.6];
scatter(x2,y2,'filled')
hold off

legend({'sin(x/2)','2016'},'Location','northwest','Orientation','horizontal')%水平

legend添加标题

lgd = legend;
lgd.FontSize = 14;
lgd.Title.String = '2016 Data';

嵌套的bar

x = [1 2 3 4 5];
y1 = [.2 .4 .6 .4 .2];
b1 = bar(x,y1);

hold on 
y2 = [.1 .3 .5 .3 .1];
b2 = bar(x,y2,'BarWidth',0.5);

y3 = [.2 .4 .6 .4 .2];
s = scatter(x,y3,'filled');
hold off

legend([b1 b2],'Bar Chart 1','Bar Chart 2')

加变量有2种方式

1. title(sprintf("%d次拟合曲线", i))
2. title ( ['运行时间: ',num2str(i) ] );

注意事项
title这句代码需要放在Plot()后面

示例

x=0:0.1:1;
y=[-0.447 1.798 3.28 6.18 7.02 7.32 7.88 9.56 9.56 9.30 11.2];
 
figure('NumberTitle', 'off', 'Name', '比较多次多项式最小二乘拟合曲线');  %%自定义新窗口名称
for i=1:4
p=polyfit(x,y,i);
xi=linspace(0,1,100);
yi=polyval(p,xi);
 
disp(i)
subplot(2,2,i)
plot(x,y,'o',xi,yi);
title(sprintf("%d次多项式最小二乘拟合", i))
end
