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?

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]);
For more information refer to the following link:

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?
