How to change the color of the connections in plot to only one color?

2 views (last 30 days)
I am trying to make a chord diagram using the code from here (https://www.mathworks.com/matlabcentral/fileexchange/48576-circulargraph) but i am unable to change the nodes name and the color of the lines to only one color. Can anyone please help me with this.

circularGraph(links1);
[row2,col2,v2] = find(links1); %v2 will create Nx1 matrix of all correaltion values
map = colormap(hot); %intialize colormap, change the color map scheme to one of your choice
minv = min(v2(:)); %min max to establish bounds of colormap
maxv = max(v2(:));
ncol = size(map,1);
s = round(1+(ncol-1)*(v2-minv)/(maxv-minv)); %scale indicies for conversion
rgb_image = ind2rgb(s,map); %convert scaled indicies to RGB, gives Nx1X3 matrix
defaultColorMap = reshape(rgb_image, [length(v2) 3]); %reshape into Nx3 matrix

To set the node labels, you can specify them with the 'Labels' input argument to circularGraph.
To set the colormap, you can specify it with the 'Colormap' input argument to circularGraph.
