【问题描述】:
好的,我对这方面真的很陌生,所以请多多包涵。我正在尝试使用来自网络上其他来源的图像的自定义 HTML 工具提示创建一个 Google 交互式折线图。但我不能让它工作;它甚至不会出现。这是我目前所拥有的(由developers.google.com 指导):
<html>
<head>
<!--Load the AJAX API-->
<script type="text/javascript" src="https://www.google.com/jsapi"> </script>
<script type="text/javascript">
// Load the Visualization API and the chart package.
google.load('visualization', '1.0', {'packages':['corechart']});
// Set a callback to run when the Google Visualization API is loaded.
google.setOnLoadCallback(drawChart);
// Callback that creates and populates a data table,
// instantiates the chart, passes in the data and
// draws it.
function drawChart() {
// Create the data table.
var dataTable = new google.visualization.DataTable();
dataTable.addColumn('string', 'Date');
dataTable.addColumn('number', 'Slices');
dataTable.addColumn({'type': 'string', 'role': 'tooltip', 'p': {'html': true}});
dataTable.addRows([
['January 1, 2015', 3, '<img width=100px src="https://upload.wikimedia.org/wikipedia/commons/2/28/Flag_of_the_USA.svg">'],
['January 2, 2015', 2, '<img width=100px src="https://upload.wikimedia.org/wikipedia/commons/2/28/Flag_of_the_USA.svg">'],
['January 3, 2015', 5, '<img width=100px src="https://upload.wikimedia.org/wikipedia/commons/2/28/Flag_of_the_USA.svg">'],
['January 4, 2015', 4, '<img width=100px src="https://upload.wikimedia.org/wikipedia/commons/2/28/Flag_of_the_USA.svg">'],
['January 5, 2015', 2, '<img width=100px src="https://upload.wikimedia.org/wikipedia/commons/2/28/Flag_of_the_USA.svg">']
]);
// Set chart options
var options = {
tooltip. {isHtml: true},
focusTarget: 'category',
'title':'How Much Pizza I Ate',
'width':900,
'height':400,
legend: { position: 'bottom' }
};
// Instantiate and draw our chart, passing in some options.
var chart = new google.visualization.LineChart(document.getElementById('chart_div'));
chart.draw(dataTable, options);
}
</script>
</head>
我知道我可能做错了什么。我会很感激有人的帮助。谢谢!
