How can I rotate a marker by a desired angle/azimuth on the map?

Hello,

I am struggling to find a method of rotating a point on a map i.e. marker (currently i use a common 'o' marker with a defined color scale indicating an azimuth of the point/marker) by certain angle on the map?

Additionally, I would also like to change the type of marker from an 'o' type to an arrow (or a even line) indicating the direction. Can you help?

Take a look at Quiver. I think that is what you are looking for.

quiver() works fine in placing markers on the plotted graph. Following example illustrates drawing marker at various angles and positions.

x=5; 
y=5; 
r=1; 
theta=0; 
for theta=0:90:360 
    x=x+3; 
u = cos(theta).*r; 
v = sin(theta).*r; 
hold on 
quiver(x,y,u,v); 
end 
axis([1,24,1,10]);

Hi,

How can we rotate a marker, like let's say '+' for example. Quiver function rotates the line which is under the property 'LineStyle' and not 'Marker'.

Also, I don't see any such property under the plot and scatter functions as well.

Can anyone provide more information in this regard?
