Thank you Tiago, that worked! A problem I have however is that I need to make the images of a reasonable size so that I can read them properly once printed but that they then start overlapping. I can of course counteract that by increasing the canvas size but if I print on A4 all that means is that the whole image is then scaled down again so it becomes illegible once more. Is there a way of keeping vertices from overlapping? (This is a very similar problem to the one outlined on stackoverflow here: https://stackoverflow.com/questions/37559695/stop-vertexes-from-overlapping-... <https://stackoverflow.com/questions/37559695/stop-vertexes-from-overlapping-eachother-when-drawing-using-graph-tool> ) -- View this message in context: http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/...
