Is there a way to alter the edge opacity in Python igraph?

Question

我知道您可以在绘图函数中调整图形的整体不透明度（opacity = (0 to 1)），但我在手册或在线搜索中找不到任何关于改变边缘不透明度（或透明度）的内容？

Answer 1

Edge opacity can be altered with the color attribute of the edge or with the edge_color keyword argument of plot() . The colors that you specify there are passed through the color_name_to_rgba function so you can use anything that color_name_to_rgba understands there; the easiest is probably an (R, G, B, A) tuple or the standard HTML #rrggbbaa syntax, where A is the opacity. Unfortunately this is not documented well but I'll fix it in the next release.
