Each cell in a data table has a Value(used as the id) and
FormattedValue(what is shown).
IIRC, this used to be documented but I don't see it in the Treemap page.
The following example does as you wish;
function drawVisualization() {
// Create and populate the data table.
var data = google.visualization.arrayToDataTable([
['Child' , 'Parent', 'Size', 'Color'],
['Global', null, 0, 0],
['Child1', 'Global', 0, 0],
['Child2', 'Global', 0, 0],
[{v:'ChildA1', f:'ChildA'}, 'Child1', 10,
0],
[{v:'ChildB1', f:'ChildB'}, 'Child1', 10,
0],
[{v:'ChildA2', f:'ChildA'}, 'Child2', 10,
0],
[{v:'ChildB2', f:'ChildB'}, 'Child2', 10,
0]
]);
// Create and draw the visualization.
var treemap = new google.visualization.TreeMap(document.getElementById(
'visualization'));
treemap.draw(data, {
minColor: 'red',
midColor: '#ddd',
maxColor: '#0d0',
maxDepth: 2,
headerHeight: 15,
fontColor: 'black',
showScale: true});
}
