Asked by Russ on 25 Nov 2012

I can't seem to find a function in Matlab that allows me to plot a hodograph. Any ideas?

I do have an answer to connect the points here is the simple Hodograph example. However, i am not sure if the wind direction is correctly displayed. I am sure i am doing something wrong there. Any suggestions to make the wind directions correct??

if true %code Ws = [6.4;6.7;7.4;7.4;7.7;7.9;8.5;8.9;9.1;9.5]; Wd = [185;186;183;186;186.5;187;191;192;197;193]; H = [40;52;60;80;100;108;140;160;180;200]; Wd = Wd.*(pi/180); Ws = Ws; [U, V] = pol2cart(Wd, Ws); polar(U, V,'ob'); text(U, V, num2str(H)); %WdXi = flipud((min(WdX):0.1:max(WdX))'); %WsYi = interp1(WdX, WsY, WdXi,'spline' ); %hold on; %polar(WdXi, WsYi); t = 1:numel(Ws); ts = 1:1/numel(Ws):numel(Ws); xs = pchip(t,U,ts); ys = pchip(t, V, ts); hold on; polar(xs, ys,'r'); end

Did you find a solution to plot a hodgraph. I seem to find a solution to plot the points but since i am not a Matlab expert. I cannot find a way to connect the points within the hodograph...I am positing a minimal example here

It would be great if you would write the solution you came to. I am unable to think of something to connect the points within the polar plot
