In the r-markdown document given below, I use tabbed sections to display sankey plots.
However, when a sankey plot is in a tab other than the first, adjusting (using htmlwidgets::onRender function) does not work. Does anybody know a way to overcome that problem?

### Outturn
```{r }
sn <- sankeyNetwork(Links = links, Nodes = nodes,
Source = "source", Target = "target",
Value = "value", NodeID = "name",
fontSize= 15, nodeWidth = 20, margin = list(left = 100),
colourScale = JS("d3.scaleOrdinal(d3.schemeCategory20b);"))
onRender(
sn,
'
function(el, x) {
d3.selectAll(".node text").attr("text-anchor", "begin").attr("x", 20);
}
'
)
```
### Actual
```{r }
sn <- sankeyNetwork(Links = links, Nodes = nodes,
Source = "source", Target = "target",
Value = "value", NodeID = "name",
fontSize= 15, nodeWidth = 20, margin = list(left = 100),
colourScale = JS("d3.scaleOrdinal(d3.schemeCategory20b);"))
onRender(
sn,
'
function(el, x) {
d3.selectAll(".node text").attr("text-anchor", "begin").attr("x", 20);
}
'
)
```
If you add the following code to the end of your example, the appropriate text-anchors will be set whenever a tab is clicked/activated, which should solve your specific problem...
```{js}
setTimeout(function () {
$('.nav-tabs a').on('shown.bs.tab', function() {
d3.selectAll(".node text").attr("text-anchor", "begin").attr("x", 20);
})
}, 1)
```
You could also then remove all of your calls to onRender further up since they're no longer needed.
Here's a full example with a bit of reformatting to make it more concise...

This might help (largely inspired from here). The idea is to rewrite the HTML code of tabsets from scratch (using htmltools) and define the same class for each tab item: 'tab-pane active'. The drawback of this approach is that it makes both plots visible before clicking on a tab. To solve this issue, we can add a JS script as a workaround that waits 1 millisecond before automatically switching to a tab.
