我想知道是否可以在Google图表中添加公司名称或公司徽标。我有一个类似下面给出的图表。我想在屏幕截图中给出的图表标题右侧添加徽标或公司名称。
我正在使我的图表可下载。所以我不能添加公司名称作为叠加层。如果我还可以添加水印,那就太好了。
google.charts.load('current', {'packages':['line']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('number', 'Day');
data.addColumn('number', 'Guardians of the Galaxy');
data.addColumn('number', 'The Avengers');
data.addColumn('number', 'Transformers: Age of Extinction');
data.addRows([
[1, 37.8, 80.8, 41.8],
[2, 30.9, 69.5, 32.4],
[3, 25.4, 57, 25.7],

var options = {
chart: {
title: 'Box Office Earnings in First Two Weeks of Opening',
},
width: 900,
height: 500,
axes: {
x: {
0: {side: 'top'}
}
}
};
var chart = new google.charts.Line(document.getElementById('line_top_x'));
chart.draw(data, google.charts.Line.convertOptions(options));
}
