I am trying to create a simple Sankey diagram showing flows between two
sets of nodes, and would like the two sets to have the same names. However,
this isn't allowed (it brings up a "Cycle found in rows" error), so I add
"2" to the names of the nodes in the second set, like so:
function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('string', 'From');
data.addColumn('string', 'To');
data.addColumn('number');
data.addRows([
['foo', 'foo2', 6],
['bar', 'bar2', 4],
['foo', 'bar2', 6],
['bar', 'foo2', 4]
]);
var chart = new
google.visualization.Sankey(document.getElementById('sankey_basic'));
chart.draw(data);
}
However, I don't want the node labels to say "foo2" and "bar2" -- I just
want them to say "foo" and "bar". In some cases in Google Visualization API
you can solve this problem with {v: 'foo2', f: 'foo'} and {v: 'bar2', f:
'bar'}, but that doesn't work here. Is there any way I can do this?
