Question

I tried to plot graphs on MATLAB using GraphViz, using this GraphViz interface.

I keep getting this error:

>> [x,y]=draw_dot(G)
??? Attempted to access node_pos(2); index out of bounds because numel(node_pos)=1.

Error in ==> dot_to_graph at 94
        y(lst_node) = node_pos(2);

Error in ==> draw_dot at 30
[trash, names, x, y] = dot_to_graph(tmpLAYOUT);  % load NEATO layout

Whats really bugging me is that it worked great before (on my old computer).

Any idea how to solve this problem?

Answer 1

After debugging, I find the solution.
Just find the line 92 in dot_to_graph.m, as written:

[node_pos] = sscanf(line(pos_pos:length(line)), ' pos  = "%d,%d"')';

Change the %d,%d to %f,%f. Because there are float numbers in the dot file.
