matlab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。" j+ [/ d% I! L7 v% L, y) k
效果如下:* S2 l4 W; D* r& j2 Z& k
1 K3 d1 p0 D: o3 ~/ I. j; }

9 a' o$ P( ?: t# s: JYou 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]);

The default values persist until you quit MATLAB. To remove default values during your MATLAB session, use the reserved word remove.
