Hi @junaidpkhader

Thanks! I'm not sure if formatter is supported in Sankey diagram and buggy or it's a bug in the docs, @TorsteinHonsi ?

According to the docs:

Options for the data labels appearing on top of the nodes and links. For sankey charts, data labels are visible for the nodes by default, but hidden for links. This is controlled by modifying the nodeFormat, and the format that applies to links and is an empty string by default.

And nodeFormat docs:

nodeFormat: String
The format string specifying what to show for nodes in the sankey diagram.

Defaults to {point.name}.

Thanks for the reply @pawelfus . Yes, I tried the nodeFormat as well. (The thing is I am unable to even write a ternary function in the nodeFormat).

Is there any way to call a function(similar to that in the formatter) in nodeFormat? (I was only able to give a string [eg. {point.name}]). We wanted to trim last part of the datalabel based on a condition.

As you might have already seen in the jsfiddle, in the sankey diagram, we are unable to show the change from the same stage. (In the fiddle, to override that we gave Contact to Contact1) [And I need to trim the "1" from Contact1 so that we can show the diagram as I just told before.]
Thank you.

I agree, something like nodeFormatter() would be great here. Thank you for the details!

Yes @pawelfus . Hope something like that would come soon.
