Gradient along links in D3 Sankey diagram

阅读更多关于 Gradient along links in D3 Sankey diagram

Here is jsfiddle of a Sankey diagram : I am trying to modify colors of the links so that the color of each link is actually gradient from its source node color to its target node color. (it is assumed that opacity will remain 0.2 or 0.5 depending whether a mouse hovers or not over the link; so links will remain a little "paler" than nodes) I took a look at this nice and instructive example , which draws this gradient filled loop: However, I simply couldn't integrate that solution to mine, it looks too complex for the given task. Also, note that links in original Sankey diagram move while node

问题 This may sound like a very broad question, but if you'll let me describe some details I can assure you it's very specific . As well as discouraging, frustrating and rage-inducing. The following plot describes a scottish election and is based on code from plot.ly: Plot 1: Dataset 1: data = [['Source','Target','Value','Color','Node, Label','Link Color'], [0,5,20,'#F27420','Remain+No – 28','rgba(253, 227, 212, 0.5)'], [0,6,3,'#4994CE','Leave+No – 16','rgba(242, 116, 32, 1)'], [0,7,5,'#FABC13',

d3 sankey charts - manually position node along x axis

阅读更多关于 d3 sankey charts - manually position node along x axis

A problem I have come across using the d3 sankey implementation is that there's no way to specify where on the x axis a node is. I've been poking through the source and there isn't really a "clean" way to specify the x value on a reasonable scale (ie, 1-5 where the chart is 5 nodes wide). I am creating something that can be used like a course planner for education, so the x value will correspond with the semester. Supposing I had a course I couldn't take until my sophomore year of college, this would be at an x of 3 (1/2 are freshman, 3/4 sophomore, etc). The problem is, if there is nothing

问题 I've created a sankey diagram in rCharts but have one question. How do I add color? I'd like to represent each node with a different color so it's easier to vizualize the paths, instead of just seeing the same grey lines connecting everything. Code and output below: require(rCharts) require(rjson) x = read.csv('/Users/<username>/sankey.csv', header=FALSE) colnames(x) <- c("source", "target", "value") sankeyPlot <- rCharts$new() sankeyPlot$set( data = x, nodeWidth = 15, nodePadding = 10,

I am trying to visualize my data flow with a Sankey Diagram in R. I found this blog post linking to an R script that produces a Sankey Diagram, unfortunately it's quite raw and somewhat limited (see below for sample code and data). Does anyone know of other scripts—or maybe even a package—that is more developed? My end goal is to visualize both data flow and percentages by relative size of diagram components, like in these examples of Sankey Diagrams . I posted a somewhat similar question on the r-help list , but after two weeks without any responses I'm trying my luck here on stackoverflow.
