plot angular distribution in matlab with a specified axis.

Hi all, I have an image with data points scattered in it. I want to define an axis, and see how the data points are distributed with respect to the given axis(angular distribution). I tried the polar plot, but it takes the existing axis of image and makes angular distribution with respect to that axis.

I have attached an image. It shows blue and red dots. I want to define the axis as mentioned in the image. I tried couple of mathematical slope, line , parallel line stuff, but not able to arrive at anuthing. Any idea is appreciated.

Thank you Avinash

% Plot with unspecified axis

x=0:1:50;
y=sin(x);
plot(x,y)

% Plot with specified axis (from 0 to 25 in x axis and -2 to +2 in y axis)

x=0:1:50;
y=sin(x);
figure, plot(x,y)
axis([0 25 -2 +2])

Hi, thank you. This only adds limits to the existing axis . I want to change the axis completely.

Thank you
