how to add labels of the nodes using sankey_plot command in stata?

[Shinyae Noh]

Hi. I am having trouble labeling the nodes...

I want to label the values at each node. However it does not showing up. My command is
gen x0 = 1 gen x1 = 2
contract x0 x1 A B, freq(freq2)
sankey_plot x0 A x1 B, ///
width0(freq2) ///
extra adjust ///
colorpalette(viridis, opacity(40)) ///
gap(0.1) noline ///
xlabel(1 "A" 2 "B", nogrid)

A represents the first node and B represents the second node.
But it turns out nothing.

So I add label0(A) label1(B) in the command, but it gives me an error code" variable A not found r(111); "

Anyone can help me?

Thank you in advance!

I think what you need to do is label all the values of variables A and B
the command should pick them up and use them in the figure

Thank you FernandoRios! I've referred to your method a lot.

Back to the question, all values of A and B are already labeled... and I am so curious that sankey_plot with wide options works well, and nodes are well labeled.

Excellent!
I ll check again what is going on with the labels in the other case. But right now have limited access to a desktop.
if you follow my site tho, I ll post the update there
