使用对象表示法,您可以提供值(v:
)和格式化值(f:
)
{v: 4.2, f: '01:16:04'}
仪表图表将显示格式化值
请参阅以下工作代码段...
google.charts.load('current', {
callback: function () {
var data = google.visualization.arrayToDataTable([
['Label', 'Value'],
[' ', {v: 4.2, f: '01:16:04'}]
]);
var options = {
height: 240,
max: 5,
minorTicks: 5,
redFrom: 3.25,
redTo: 5,
yellowFrom: 1.65,
yellowTo: 3.25,
width: 240
};
var chart = new google.visualization.Gauge(document.getElementById('chart_div'));
chart.draw(data, options);
},
packages:['gauge']
});
