[SOLVED]
I am trying to do a ShinyApp using some examples from the internet. As part of my app I want to plot a Sankey Diagram, however, I have been finding a problem.
My app has a navbarPage structure and uses the example from https://github.com/jienagu/D3_folded_charts as one of the primary tabs. After some tests, I figured out that the sankeyNetwork was in conflict with the code part of the bar graph in the example above (specifically with this part: lines 147-149):
output$airbar = renderD3({ bar_graphD3() })
This is the code I am using to render the Sankey diagram:
output$diagram <- networkD3::renderSankeyNetwork({
networkD3::sankeyNetwork(Links = dispersores_df,
Nodes = nodes,
Source = "IDsource",
Target = "IDtarget",
Value = "value",
fontSize = 20,
NodeID = "name",
sinksRight=FALSE)
})
Since this bar graph function is very important for my app, I can't remove it.
Also, due to the fact that the console doesn't pop up any error message, I realized the sankeyNetwork was been rendered. So, I changed my app structure to the fluidPage() and I found the Sankey graph was there (but it was not interactive) as you can see in the figure below.
Sankey visualized in the fluidPage() structure
After changing back to navbarPage() I inspected the tab the Sankey was, and it looks like it is there but invisible.
Sankey invisible in the navbarPage() structure
I found a similar report here sankeyNetwork through renderUI disappears when applying JScode to remove viewbox with htmlwidgets::onRender() but its solution didn't work for me.
Does anyone have any idea or clues that could help me?
Thanks
