この Google Chart Scatter Plot で score.partner をラベルとして表示できないようです。それらをツールチップとして表示することしかできません。
私は何を間違っていますか?
drawChart: function() {
var self = this;
var gdpMin = parseFloat(self.scores[0].gdpScore);
var gdpMax = gdpMin;
var teaMin = parseFloat(self.scores[0].teaScore);
var teaMax = teaMin;
var data = new google.visualization.DataTable();
data.addColumn('number', 'GDP Score');
data.addColumn('number', 'TEA Score');
data.addColumn({type:'string', role:'label'});
$.each(self.scores, function(i, score) {
gdpScore = parseFloat(score.gdpScore);
teaScore = parseFloat(score.teaScore);
data.addRows([[gdpScore, teaScore, score.partner]]);
if (gdpScore < gdpMin) gdpMin = gdpScore;
if (gdpScore > gdpMax) gdpMax = gdpScore;
if (teaScore < teaMin) teaMin = teaScore;
if (teaScore > teaMax) teaMax = teaScore;
});
var options = {
title: 'GDP and TEA Scores',
hAxis: {title: 'GDP', minValue: gdpMin, maxValue: gdpMax},
vAxis: {title: 'TEA', minValue: teaMin, maxValue: teaMax},
legend: 'none',
colors: ['#3B7CBF']
};
var chart = new google.visualization.ScatterChart(document.getElementById('chart_div'));
chart.draw(data, options);
