anwfr opened a new issue #10931: Sankey - custom link tooltip
URL: https://github.com/apache/incubator-echarts/issues/10931
 
 
   ### What problem does this feature solve?
   Hello, I would like to customize link tooltip in Sankey.
   Currently link hover produces the following tooltip: "{source} -- {target} : {value}"
   
   ### What does the proposed API look like?
   Custom link tooltip could be set as a link property:
   {
             source: "source",
             target: "target",
             tooltip: {
               formatter: "custom link tooltip"
             }
   }
