效果如下:
! G/ ^+ L6 k8 [* Z- I% T+ {1 Z" k$ W3 ^9 y# q1 u
8 d) T% o' t/ V; X0 Z/ ~
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。) r2 d) h' C0 K# n. b
! E6 c: X o3 M" {- o6 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]);
! C/ j: a0 D% z5 j6 @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.
