I am currently trying to project the point along the direction of the normals.However my current method tends to project them in a diagonal manner.
The original img
Now i use this code to ensure that my points are displayed in correct order(Note I can always do set(gca'YDir','reverse') )
h = findobj(gca,'Type','line');
After this when I plot the normals I get this figure,any idea what is happening here
