Hello Tiago, Thanks for the reply. I have attached my full code along with the necessary data file. Can you please try to run it and see what is the problem? Thank you Snehal On Mon, Dec 12, 2016 at 5:32 PM, Tiago de Paula Peixoto <tiago@skewed.de> wrote:

Hello all,

I am encountering a strange error in the usual gt.graph_draw when I add vertex_size = degree. It works well every time but this time it is not working. My code:

G = gt.Graph(directed = False) G.add_edge_list(edges, hashed = True, string_vals = True) gt.remove_parallel_edges(G) lc = gt.Graph(gt.GraphView(G, vfilt = gt.label_largest_component(G)), prune = True)

deg = lc.new_vertex_property('int') for v in lc.vertices(): deg[v] = v.out_degree()

print(lc) gt.graph_draw(lc, vertex_size = deg)

And I am getting the following error:

Traceback (most recent call last): File "/usr/lib/python3/dist-packages/graph_tool/draw/gtk_draw.py", line 503, in draw self.fit_to_window(ink=False) File "/usr/lib/python3/dist-packages/graph_tool/draw/gtk_draw.py", line 724, in fit_to_window cr) File "/usr/lib/python3/dist-packages/graph_tool/draw/cairo_draw.py", line 1319, in fit_to_view font_size, cr) File "/usr/lib/python3/dist-packages/graph_tool/draw/cairo_draw.py", line 1292, in get_bb x_delta = [x_range[0] - (pos_x.fa - delta).min(), ValueError: operands could not be broadcast together with shapes (4,) (3397,)

I have 3397 vertices in my graph. I would greatly appreciate any help. Thanks in advance.

I can't reproduce this. Please provide a complete, self-contained program that shows the error. (In the example above the list of edges is missing).

Best, Tiago

Thanks.. that worked! A small related question: The nodes in my graph are strings and that's why I am using `hashed = True` and `string_vals = True`. How can I use these values as labels for my nodes while drawing the graph? I couldn't find any way to extract these strings to define a new property map for vertex_text.

Hi,

Indeed there is a bug in the interactive drawing for large graphs. I will fix this soon.

In the meantime, a simple workaround is to get the vertex positions explicitly:

pos = gt.sfdp_layout(lc) gt.graph_draw(lc, pos=pos, vertex_size=deg)

Best, Tiago

The Graph.add_edge_list() method already returns the property map you want.
