先定义几个变量:
, r# I8 n+ v% B" x; U- Q0 R+ I. Jx = 0:pi/10:2*pi;) @7 t1 w* u" \$ P, j
y1 = sin(x);& h; {- ^( [$ Q' }# o" B
y2 = sin(x-pi/2);
$ S! _3 R8 p6 u3 V8 Z$ j e# Z% Fy3 = sin(x-pi);
* g$ k2 H1 ^, u i
. ^) j! d& b* r/ v$ E8 k8 v( b
' R1 h2 ^# h4 @+ A! B" E5 Hmatlab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。) G4 i. Z+ Z! U- \2 L+ q
效果如下:
$ E+ _4 ?7 s- K5 D7 o" P; w
/ p! G% m" G% A# e# O @! _
) j0 i r# z9 z- y" ]! g6 h& g
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。

H4 I6 \& q# E) m# A* [* O$ M( _) T" B: tYou 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]);' b) |: `1 C$ L$ G' x7 K$ d
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:

The default values persist until you quit MATLAB. To remove default values during your MATLAB session, use the reserved word remove." x! O+ R) t1 Z6 Z2 Z
