My workaround for this, was adding event on 'ready' after draw a chart like:
google.visualization.events.addListener(chart, 'ready', function() {
and replace values with formated one (it's not so clean code but i hope
it's gonna help someone)
Event
google.visualization.events.addListener(chart, 'ready',
function(e) {
$('.chart').find('svg g text').each(function(){
var value = $(this).html();
value = value.replace('%', '').replace(',', '.');
value = Number(value).formatNumber(2, ',', ' ');
$(this).html(value+'%');
});
});
Formater function
Number.prototype.formatNumber = function(c, d, t) {
var n = this,
c = isNaN(c = Math.abs(c)) ? 2 : c,
d = d == undefined ? "." : d,
t = t == undefined ? "," : t,
s = n < 0 ? "-" : "",
i = parseInt(n = Math.abs(+n || 0).toFixed(c)) + "",
j = (j = i.length) > 3 ? j % 3 : 0;
return s + (j ? i.substr(0, j) + t : "") +
i.substr(j).replace(/(\d{3})(?=\d)/g, "$1" + t) + (c ? d + Math.abs(n -
i).toFixed(c).slice(2) : "");
};
