1实现方法
大部分实现方法都是保存为图片后再扭曲，欸，我就要直接画，就是玩。
2代码使用
很简单，就只需要加一行 comicAxes([]) 即可
3demo
代码
x=1:0.1:10;
y1=sin(x).*exp(-x/3) + 3;
y2=3*exp(-(x-7).^2/2) + 1;
ax=gca;
ax.XLim=[1,10];
ax.YLim=[-1,5];
hold(ax,'on')
grid on
box on
plot(x,y1,'b');
plot(x,y2,'r');
title('I am title')
xlabel('I am xlabel')
ylabel('I am ylabel')
lgd=legend({'line1','line2'},'location','southeast');
title(lgd,'a sub title')
% annotation一定要被添加至UserData才能被检测到
ax.UserData{1}=annotation(ax.Parent,'textarrow',[0.4 0.56],[0.74 0.67],'String',{'text','here'},'HorizontalAlignment','left');
get(ax.UserData{1})
comicAxes(ax)

后
代码
t=0:0.1:3*pi;
plot(t,sin(t),'Color',[0.4 0.76 0.65])
hold on
grid on
plot(t,cos(t./2),'Color',[0.99 0.55 0.38])
plot(t,t,'Color',[0.55 0.63 0.8])
lgd=legend('y=sin(t)','y=cos(t/2)','y=t');
lgd.Location='northwest';
title(lgd,'Func','FontSize',12)
comicAxes([])

后
代码
t=1:10;
y1=rand([1,10])*15;
plot(t,y1)
hold on
grid on
tq=1:0.1:10;
y2=interp1(t,y1,tq,'spline');
plot(tq,y2)
y3=interp1(t,y1,tq,'makima');
plot(tq,y3)
lgd=legend('linear','spline','makima');
lgd.Location='northeast';
title(lgd,'method','FontSize',12)
saveas(gcf,'1.png')
