How can I plot something like this ?

Hello everybody,

I have a hard time finding the right approach for plotting my data like in the photo. Each branch corresponds to a direction and the intersection is the origin. Does anyone know a classical way to do this?

You have to think how to draw many lines with different colors. I'd use jet() colormap

Simple example

cm = jet(256);                                 % create 256 colors of jet() colormap
h(1) = plot([0 1],[0 1],'COlor',cm(220,:));    % draw red line
hold on
h(2) = plot([1 2],[1 2],'Color',cm(190,:));    % draw orange line
h(3) = plot([2 3],[2 3],'Color',cm(160,:));    % draw yellow line
hold off
set(h,'LineWidth',5);

Hello,

Thank your for your answer. I actually did some research and I ended up doing this:

x = linspace(-8,0,n); y = x;

% p = plot(x,y,'r', 'LineWidth',5);

%

% % modified jet-colormap

% cd = [uint8(jet(n)*255) uint8(V)].';

%

% drawnow

% set(p.Edge, 'ColorBinding','interpolated', 'ColorData',cd)

%

Now what I didn't figure out is how to display the colorbar to see the values. Do you know how to do it?

Always search the help first for the most obvious key words. In this case not only a keyword, but an actual function with exactly the name you would expect!
