Fixed vertex size between different layouts
by Botond Molnár 03 Aug '21

03 Aug '21

Hello, I am trying to plot a few networks using two different layouts. The vertex sizes and edge width are calculated separately, then each networks is plotted using two different layouts: radial tree layout and sfdp layout. In both cases the same pre-calculated values are used to set the vertex sizes and edge width, in order to maintain the comparability of the plots. However, I end up with different vertex sizes and edge width in function of the chosen layout. I am using the cairo backend, so I can plot both layouts next to each other, but the ax sizes are the exactly the same. Can you please help me how can I sort this out? Thank you in advance, Botond

Adding property maps of custom types
by sebyakin.a 03 Aug '21

Hello, My question is: which parts of a code I should modify to add internal property maps of custom type? Is it possible without ground-breaking modifications, or should I look a way for some workaround? My usecase is to bridge python integer objects and big integer objects (from intx library) on c++ side, as a vertex property. I'm going to perform relatively heavy math operations and graph operations, so I want to write a C++ extension that does it. So I thought, is it possible to add custom property map handlers for big integers, that will convert python long objects to intx type and store it in that type later.
