Hmm. This is a good bug/feature request.
So, I have a workaround, but it's kludgey. Basically, what you can do is
set your datatable (at the rows where you don't want to display the label)
as: ' ', ' ', ' ', for the titles. So:
var data = google.visualization.arrayToDataTable([
['Location', 'Parent', 'Market trade volume (size)', 'Market
increase/decrease (color)'],
['Global', null, 0, 0],
['America', 'Global', 0, 0],
['Brazil', 'America', 11, 10]
,
['USA', 'America', 52, 31]
,
['Mexico', 'America', 24, 12]
,
['Canada', 'America', 16, -23
],
[' ', 'Canada', 160, -23],
[' ', 'Canada', 160, -23],
[' ', 'Canada', 160, -23]
,
[' ', 'Canada', 1, -23],
[' ', 'Canada', 1, -23]
,
[' ', 'Canada', 1, -23
],
[' ', 'Canada', 1, -
23],
]);
And it will render blank spaces.
I'll file a bug internally to investigate this issue.
