How to draw a line graph in a 2D oblique coordinate system?

请教，如何画2D斜坐标系的线图？

Please tell me how to draw a line drawing in a 2D oblique coordinate system?

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

这还是直角坐标系中画线。不是画斜坐标系。

This is still a line drawn in the Cartesian coordinate system. It is not an oblique coordinate system.
