1、设置图形对象属性值
set(h,‘属性名称‘,‘属性值‘)
>> subplot(1,2,1); h1=line([0 1],[0 1]); text(0,0.5,‘unchange‘); subplot(1,2,2); h2=line([0 1],[0 1]); set(h2,‘linewidth‘,4); text(0,0.5,‘change‘);
2、基本二维绘图函数
- plot
x=0:0.25:2*pi; y=sin(x); plot(x,y,‘-ro‘,‘linewidth‘,2,‘markeredgecolor‘,‘b‘,‘markerfacecolor‘,‘0.49,1,0.65‘,‘markersize‘,14); >> xlabel(‘x‘); >> ylabel(‘y‘)
2. loglog:双对数坐标绘图
>> x=logspace(-1,2); loglog(x,exp(x),‘-s‘); grid on xlabel(‘x‘) ylabel(‘y‘)
3. semilogx,semilogy:半对数坐标绘图
>> x=-10:0.001:10; semilogy(x,2.^x);
4. polar:极坐标绘图
>> t=0:0.01:10; polar(t,sin(2*t).*cos(2*t),‘--.g‘)
5. plotyy:双纵坐标绘图
>> x=0:0.1:20; >> y1=200*exp(-0.05*x).*sin(x); >> y2=0.8*exp(-0.5*x).*sin(10*x); >> ax=plotyy(x,y1,x,y2,‘plot‘);xlabel(‘x‘); >> set(get(ax(1),‘ylabel‘),‘string‘,‘left y‘); >> set(get(ax(2),‘ylabel‘),‘string‘,‘right y‘);
3、二维图形修饰和添加注释
