当我使用带有日历套餐的Google Chart API时,如果日期是11月或12月,则不会绘制数据。
我正在使用https://developers.google.com/chart/interactive/docs/gallery/calendar上提供的Google代码示例。
而且,即使使用谷歌样本,如果我将月份更改为11月或12月(索引10或11),则数据不会被绘制,但其他月份都可以。
来自Google的示例代码:
<html>
<head>
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load("visualization", "1.1", {packages:["calendar"]});
google.setOnLoadCallback(drawChart);
function drawChart() {
var dataTable = new google.visualization.DataTable();
dataTable.addColumn({ type: 'date', id: 'Date' });
dataTable.addColumn({ type: 'number', id: 'Won/Loss' });
dataTable.addRows([
[ new Date(2012, 3, 13), 37032 ],
[ new Date(2012, 3, 14), 38024 ],
[ new Date(2012, 3, 15), 38024 ],
[ new Date(2012, 3, 16), 38108 ],
[ new Date(2012, 3, 17), 38229 ],
// Many rows omitted for brevity.
[ new Date(2013, 9, 4), 38177 ],
[ new Date(2013, 9, 5), 38705 ],
[ new Date(2013, 9, 12), 38210 ],
[ new Date(2013, 9, 13), 38029 ],
[ new Date(2013, 9, 19), 38823 ],
[ new Date(2013, 9, 23), 38345 ],
[ new Date(2013, 9, 24), 38436 ],
[ new Date(2013, 9, 30), 38447 ]
]);
var chart = new google.visualization.Calendar(document.getElementById('calendar_basic'));
var options = {
title: "Red Sox Attendance",
height: 350,
};
chart.draw(dataTable, options);
}
</script>
</head>
<body>
<div id="calendar_basic" style="width: 1000px; height: 350px;"></div>
