Matlab画图技巧：颜色设置‌

% 颜色设置 

x = linspace(0,3*pi,200);

y = cos(x) + rand(1,200);  

plot(x,y,'Color',[1 0 1]);

% 注意plot函数和scatter函数的颜色设置方法不同

scatter(x,y,[],[1 0.5 0]);

x = 0:0.01:2*pi;

y = sin(x);

plot(x,y);

xlabel(['\fontname{STSong}(长度ABCdfgem)\fontname{Times new roman} (ABCdfgem)'],"FontSize",17)

ylabel(['\fontname{SimSun}长度\fontname{Times new roman} (mm)'])

print(gcf,'-dtiff','-r600',['一个测试的图片1' ...

    'S=100.bmp']);

hold off;

figure

x = 0:0.01:2*pi;

y = sin(x);

plot(x,y);

xlabel(["长度 (mm)"])

print(gcf,'-dtiff','-r600',['一个错误的图片2' ...

    'S=100.bmp']);
