You can do something quite similar by creating a DataTable with 4 columns:
domain (axis labels), value (for the height of the lower bars), box
thickness (for the height of the colored boxes), and color:
var data = google.visualization.arrayToDataTable([
['Label', 'Value', 'Box thickness', {type: 'string', role: 'style'}],
['Foo', 20, 2, '#ff0000'],
['Bar', 25, 2, '#00ff00'],
['Cad', 15, 2, '#0000ff'],
['Qud', 27, 2, '#ff00ff']
]);
Then set the chart's "isStacked" option to true.
You will probably want to do more customization with this, as the default
behaviors for these components are probably not what you want.
