Branches with color gradient #3

Open mgerschwitzeidt opened 3 years ago

Hello, I would like to plot the evolution of a continuous trait onto a phylogenetic network. The trait values for the internal nodes were reconstructed from external node valus with phylonetworks and now I would like to color the network branches with color gradients from each parent node to its child node(s). In ggtree, I can achive that task with an aes after specifing "continuous = TRUE" (e.g. see attached figure, made from example data: https://yulab-smu.top/treedata-book/chapter4.html). Using ggtree_2.5.0.991, I can create color gradients with the tree layouts "slanted" and "rectangular" (amongst others). However, in tanggle, the feature "continuous" seems to be missing. Therefore, using an aes, the branches recieve a color corresponding to the child node only instead of a color gradient. A color gradient feature would be a great addition to tanggle. Do you think you will implement that at some point?

Thanks for your interest in tanggle! Yes, we definitely want to add this option to the package, but we are lacking manpower at the moment with a long to-do list to go through. We do expect to add this functionality at some point, but we are unable to give you a timeframe at this point, sorry!
