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。$ |: H4 N+ M. l

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]);
. o2 r) ~4 {' L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.# U7 u( I& e( ~/ c
