我正在尝试在客户端的网站中嵌入谷歌线图,这将在运行时基于一些php变量生成。我面临的问题是,我正在使用的图表的父母背景(保存图表)是rgba(0,0,0,.7)格式,它给背景提供透明的感觉而不是内容,以及谷歌api给出的背景是白色的,我试图改变背景的颜色,但它接受十六进制值“#000”,它不提供透明度。任何人都可以建议一种方法来给谷歌图表的颜色rgba()。抱歉,我无法分享确切的代码,但以下内容可以作为参考。
<html>
<head>
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
<script type="text/javascript">
google.charts.load('current', {'packages':['corechart']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Year', 'Sales', 'Expenses'],
['2004', 1000, 400],
['2005', 1170, 460],
['2006', 660, 1120],
['2007', 1030, 540]
]);
var options = {
title: 'Company Performance',
curveType: 'function',
legend: { position: 'bottom' },
backgroundColor:'#000';
};
var chart = new google.visualization.LineChart(document.getElementById('curve_chart'));
chart.draw(data, options);
}
</script>
</head>
<body>
<div id="curve_chart" style="width: 900px; height: 500px"></div>
</body>
</html>

尝试
backgroundColor: {
'fill': '#000',
'fillOpacity': 0.1
},
这使用带透明度的不透明度的十六进制颜色
