JS - 如何在 Google Graphs (slantedText) 上旋转标签 (hAxis)？
Aur*_*x22 2 html javascript axis graph google-visualization
我一直试图简单地在下图上旋转我的 hAxis 很长时间了。尝试了以下解释的几种解决方案！不敢相信这么简单的事情似乎很难做到。源代码如下：
<html>
<title>VM Allocation Performance</title>
<meta http-equiv="refresh" content="30">
<head>
<script type="text/javascript" src="http://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load("visualization", "1", {packages:["bar"]});
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['09/12/2015 10:00:00',3.52],['09/12/2015 10:30:00',7.56],['09/12/2015 11:00:00',8.99],['09/12/2015 11:30:00',4.93],['09/12/2015 12:00:00',10.26],['09/12/2015 12:30:00',9.82],['09/12/2015 13:00:00',12.62],['09/12/2015 13:30:00',9.07],['09/12/2015 14:00:00',4.94],['09/12/2015 14:30:00',8.98],['09/12/2015 15:00:00',7.85],['09/12/2015 15:30:00',3.59],['09/12/2015 16:00:00',5.64]],true);
var options = {
chart: {
title: 'VM Allocation',
subtitle: 'Since Shift Start',
}
//I tried with slantedText: true here but while my graph was rendering, labels were not rotated!
};
var chart = new google.charts.Bar(document.getElementById('chart_div'));
chart.draw(data, google.charts.Bar.convertOptions(options));
}
</script>
</head>
<body>
<div id='chart_div' style='width: 450px; height: 400px;'></div>
</body>
</html>
这是我到目前为止尝试过的：
我阅读了谷歌文档，相应地更改了我的代码（因为它是一个“材料”图等......），但仍然没有。
我尝试从这个jsfiddle使用相同的 hAxis 块我发现的，但不走运。
我进入了更多细节，并在Google 文档上看到选项“slantedText”仅适用于离散轴，所以我认为我必须将我的 hAxis 类型从日期/时间更改为字符串，我尝试过但没有成功。
我继续尝试使用这个SO 的解决方案，虽然我仍然可以渲染图形，但我的日期/时间标签仍然没有完全显示（这就是我想旋转它们的原因）。
有人可以帮忙吗？
更改为柱状图而不是条形图。见http://jsfiddle.net/Swtv3/51/
function drawChart() {
var data = google.visualization.arrayToDataTable([
['09/12/2015 10:00:00',3.52],['09/12/2015 10:30:00',7.56],['09/12/2015 11:00:00',8.99],['09/12/2015 11:30:00',4.93],['09/12/2015 12:00:00',10.26],['09/12/2015 12:30:00',9.82],['09/12/2015 13:00:00',12.62],['09/12/2015 13:30:00',9.07],['09/12/2015 14:00:00',4.94],['09/12/2015 14:30:00',8.98],['09/12/2015 15:00:00',7.85],['09/12/2015 15:30:00',3.59],['09/12/2015 16:00:00',5.64]],true);
var options = {
chart: {
title: 'VM Allocation',
subtitle: 'Since Shift Start',
},
chartArea: {
top: 28,
height: '40%'
},
hAxis: {
title: 'Sources',
slantedText: true
}
//I tried with slantedText: true here but while my graph was rendering, labels were not rotated!
};
var chart = new google.visualization.ColumnChart(document.getElementById('chart'));
chart.draw(data, options);
}
google.load("visualization", "1", {packages:["corechart"]});
google.setOnLoadCallback(drawChart);
