Firefox中sankeyNetwork(NetworkD3)的微小绘图输出

Question

由于每个对象,我用的时候获得在Firefox中非常小的情节sankeyNetwork()从networkd3在闪亮,但无法在Chrome或RStudio.

我没有在脚本中包含任何CSS或JS - 下面的代码为我生成了这个结果.

我错过了什么CSS属性吗？

我使用的是R 3.4.1,闪亮的1.1.0,networkD3 0.4和Firefox 52.9.0.

感谢@CJYetman指出onRender()可能的解决方案 - 但是当下面的MRE中有两个并排生成的图时会失败(注意除了第二个sankey图之外我还添加了javascript代码来重新绘制数字时窗口大小会随着图表自动显示而变化.

    dimension[1] = window.innerHeight;
    Shiny.onInputChange("dimension", dimension);
});
$(window).resize(function(e) {
    dimension[0] = window.innerWidth;
    dimension[1] = window.innerHeight;
    Shiny.onInputChange("dimension", dimension);
});
                            ')

------------------ EDIT2 --------------------

上面的第二个问题解决了 - 要么根据@ CJYetman在下面的评论中引用页面上的第二个svg项目document.getElementsByTagName("svg")[1].setAttribute("viewBox",""),要么通过进入对象本身选择他们的第一个svg元素document.getElementById("sankeyHSM2").getElementsByTagName("svg")[0].setAttribute("viewBox","").

这似乎是Firefox对viewboxsvg属性的反应不同于其他浏览器的结果.在此处提交此问题可能是值得的https://github.com/christophergandrud/networkD3/issues

在此期间,您可以通过viewbox使用一些JavaScript和重置属性来解决这个问题htmlwidgets::onRender().这是使用示例的最小化版本的示例.(重置viewbox属性可能会产生其他后果)

library(htmlwidgets)
library(networkD3)
library(magrittr)

nodes = data.frame("name" = factor(as.character(1:9)),
                   "group" = as.character(c(1,2,2,3,3,4,4,4,4)))

links = as.data.frame(matrix(byrow = T, ncol = 3, c(
  0, 1, 1400,
  0, 2, 18600,
  1, 3, 400,
  1, 4, 1000,
  3, 5, 100,
  3, 6, 40,
  3, 7, 20,
  3, 8, 4
)))
names(links) = c("source","target","value")

sn <- sankeyNetwork(Links = links, Nodes = nodes, Source = "source", 
                    Target = "target", Value = "value", NodeID = "name", 
                    NodeGroup = "group", fontSize = 12, sinksRight = FALSE)

htmlwidgets::onRender(sn, 'document.getElementsByTagName("svg")[0].setAttribute("viewBox", "")')
