我试图sankeyNetwork()在networkD3包中使用Sankey图.
sankeyNetwork(Links = Flow_data, Nodes = Nodes_data,
Source = "Source_ID", Target = "Target",
Value = "value", NodeID = "Nodes_name",
width = 1000, height=600, fontsize = 16, nodeWidth = 50,
colourScale = "d3.scale.category20c()")
可视化效果很好,但我想将颜色范围更改为单个范围.有没有机会改变SankeyNetwork的颜色？我需要一系列只有3种颜色,我可以自己设置(不是d3.scale的预定义colourScales).
