先定义几个变量:
5 U3 I* ^. [4 I( a: z- lx = 0:pi/10:2*pi;
) Z( g/ m- u4 C: p% z# `. y5 l ~y1 = sin(x);% o2 Z; k$ P# z% g5 q. T
y2 = sin(x-pi/2);
( W R6 \! F& a5 iy3 = sin(x-pi);
+ ~6 x2 n+ o6 a' t8 ]0 v/ R+ R4 `, q3 Q9 Z* k
8 [2 I) y: G, p: G6 omatlab作图的时候,如果直接使用plot(x,y1,x,y2,x,y3);那么matlab将自动使用不同的颜色来区别这三条曲线。, s4 N; F c7 l9 p
效果如下:
1 \5 I; g6 l3 R+ a5 W
0 ~: K/ |1 ^* H) t* X6 _
D8 ^/ Y; {' J6 ?+ i1 F5 p# W, J3 w但是有的时候,为了保证黑白打印的时候也能区分不同曲线,就要用不同线型来区分。怎么样让matlab自动做这件事呢。

You can configure MATLAB defaults to use line styles instead of colors for multiline plots by setting a value for the axes LineStyleOrder property using a cell array of linespecs. For example, the command set(0,'DefaultAxesLineStyleOrder',{'-o',':s','--+'})defines three line styles and makes them the default for all plots. To set the default line color to dark gray, use the statement set(0,'DefaultAxesColorOrder',[0.4,0.4,0.4]);
8 }/ D- U/ l& e8 @+ [8 } U1 w+ P也就是说在plot(x,y1,x,y2,x,y3);的前面加上这两句话,set(0,'DefaultAxesLineStyleOrder',{'-o',':s','--+'})set(0,'DefaultAxesColorOrder',[0.4,0.4,0.4]);这回效果如下:
1 {( B6 r0 d, l# f0 b7 G, }: s
8 ?- R1 p+ y! e
The default values persist until you quit MATLAB. To remove default values during your MATLAB session, use the reserved word remove.9 ?, R: W, g' H- g U( Z- }
