Hi,
I've been trying to retreive the Datatable row of a selected word in a
WordTree Chart and failing miserably at it.
Considering the explicit case:
var nodeListData = new google.visualization.DataTable();
nodeListData.addColumn('number', 'id');
nodeListData.addColumn('string', 'childLabel');
nodeListData.addColumn('number', 'parent');
nodeListData.addColumn('number', 'size');
nodeListData.addColumn('number', 'color');
nodeListData.addRow([0, 'Life', -1, 1, 0]);
nodeListData.addRow([1, 'Archaea', 0, 1, 0]);
nodeListData.addRow([2, 'Eukarya', 0, 5, 0]);
var options = {wordtree: {format: 'explicit'}};
var mywordtree = new
google.visualization.WordTree(document.getElementById('wordtree_explicit'));
google.visualization.events.addListener(mywordtree, 'select', myClickHandler);
mywordtree.draw(nodeListData, options);
function myClickHandler(){
//this just has 3 properties (word, weight and color)
var selectedItem = mywordtree.getSelection();
//trying with any method of the Datatable gives no results probably due to the
fact that it is not the object drawn on the page
.....
}
I would be very grateful if someone could help in this regard.
The purpose behind this effort is being able to uniquely identify a
user-selected word of the charted wordtree.
Thank you in advance.
Felipe.
