Sankey: setAction is not a function

[Gyula Kósa]

Hi! I'm following the developer guide at https://developers.google.com/chart/interactive/docs/customizing_tooltip_content#full.

I get 'Sankey chart.html:66 Uncaught (in promise) TypeError: chart.setAction is not a function' error in the browser console for the following implementation.

I'm wondering what do I wrong?

    <script type="text/javascript">

        google.charts.load("current", {packages:['sankey', 'wordtree']});

        

        google.charts.setOnLoadCallback(drawSankeyChart);

        function drawSankeyChart() {

          var data = new google.visualization.DataTable();

          data.addColumn('string', 'From');

          data.addColumn('string', 'To');

          data.addColumn('number', 'Weight');

          data.addRows([

            ...

          ]);

      

          // Set chart options

          var options = {

            width: 1000,

            tooltip: {

                trigger: 'selection'

            }

          };

      

          var chart = new google.visualization.Sankey(document.getElementById('sankey_multiple'));

      

          chart.setAction({

                id: 'remove',

                text: 'Remove',

                action: function() {

                    selection = chart.getSelection();

                    alert(selection[0].row + 'will be removed');

                    }

                });

            chart.draw(data, options);

         };

Hi, 

i don't know if you still need it, but setAction is probably not compatible with sankey. The documentation is misleading. 

See:  https://github.com/google/google-visualization-issues/issues/2349
