酱紫?
i=sqrt(-1);
x_v=1;
y_v=(1+i)/sqrt(2);%定义y轴的方向
x=1:10;
y=1:10;
data=x*x_v+y*y_v;%把原来的数据x-y变到新坐标系
x=0:10;
y=zeros(1,11);
xaxes=x*x_v+y*y_v;%把原来的x轴变到新坐标系
x=zeros(1,11);
y=0:10;
yaxes=x*x_v+y*y_v;%把原来的y轴变到新坐标系
plot(real(data),imag(data),'blue')
hold on
plot(real(xaxes),imag(xaxes),'red')
plot(real(yaxes),imag(yaxes),'red')
hold off
