How to rotate axis?

Hi , I have got some data (simulation of a blod vessel) I want to plot by Matlab. The vessel has an angle of 10 degree position from x axis, but I want it to be horizontal. I tried to use rotate command, rotate(h,direction,alpha)to rotate the axises 10 degrees, but I don't know what should I put as alpha. Is there anybody who has done it before? Is there another command I can use?

You would use an alpha of -10 to rotate 10 degrees clockwise.
