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
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.
