I am trying to plot a hodograph plot as shown below. With the heklp of polar plot i could plot the points, however, i don't know how to connect a spline in between those points. Is it possible to do it somehow. I am posting my MWE.

Nomenclature:

Ws - wind speed in m/s
Wd - wind direction in degrees
H - height for which the points are present in m

Ws = 15.*rand(10,1);
Wd = 360.*rand(10,1);
H = (20:20:200)';
Wd = Wd.*(pi/180);
[WdX, WsY] = pol2cart(Wd, Ws);
polar(WdX, WsY,'-b*');

Have you tried to connect your points with splines? See http://www.mathworks.se/help/matlab/examples/splines-in-two-dimensions.html for an example.

Oh Thanks Matz....

I was actually working with splines but through the interp1 function. However, was not getting the way i wanted it.

I tried working with the example you showed and applied it on my example and it works perfectly. Will be conditioning it further to get the best results but so far, thats a good step.

Thanks and keep the good work
