[求助]MATLAB的二维绘图的问题

[李寅]

通过低层的绘图操作,运用实验数据或者自产生的序列 或者自定义函数 自定义坐标轴 通过编程实现 二维图形的绘制 并且,要求对所绘制的图形有相应的标注对应.(设置多个图形比如背景颜色可自定义变化;线形宽度:形状可改变:标记符:组合键的设置:网格线的开关,坐标轴的有无等等.)
screen=get(0,'screensize')
W=screen(3);H=screen(4);
figure('color',[1,1,1],'position',[0.2*H,0.2*H,0.5*W,0.3*H],...

这里面线形宽度:形状可改变怎么加程序?????并且希望有讲解!!!!谢谢了 我是新手 还请大家帮帮我....:lovely: :lovely: :lovely: :lovely: :lovely:
