Calculating node coordinates for a graph without plot command

Hello,

I'm using a custom plotting routine for a graph, to which I want to provide node coordinates that are calculated for a good representation. I have found a solution by plotting the graph in an invisible plot and extracting the coordinates:

s = [1 1 2 2 3];

t = [2 4 3 4 4];

G = digraph(s,t);

fig = figure('Visible', 'off');

h = gca;

graphPlot = plot(h,G,'layout', 'force','WeightEffect','direct');

allCoordinates(:,1) = graphPlot.XData

allCoordinates(:,2) = graphPlot.YData

close(fig);

However, this is quite inefficient... Is there a way to do this, without using the plotting routine?

Thanks!

Unfortunately there isn't a way to get these coordinates without plotting. I have added your request for such a function to our internal tracker for new functionality requests.
