….在我的例子中

http://jsfiddle.net/ETFairfax/78595a3h/

…工具提示正在对条形数值进行四舍五入,而不是仅显示它们的值.

我已经尝试自定义工具提示,如下所示：https://developers.google.com/chart/interactive/docs/customizing_tooltip_content#custom_html_content,但仍然没有喜悦.

文件确实说…

“The Material Charts are in beta.”

所以也许我正在打败一个失败的事业.

我的问题：

有谁知道如何阻止工具提示四舍五入？

任何帮助赞赏.

HTML

<div id="chart_div" style="width: 900px; height: 500px;"></div>

JS代码：

google.load("visualization","1.1",{
    packages: ["bar"]
});
google.setOnLoadCallback(drawChart);
 
function drawChart() {
    var data = google.visualization.arrayToDataTable([
        ['Task','Hours per Day'],['Work',8.5],// Tooltip says 8.5. CORRECT
        ['Eat',11.5],// Tooltip says 12 - INCORRECT
        ['Commute',2],// Tooltip says 2 - CORRECT
        ['Watch TV',0.28],// Tooltip says 0.28 - CORRECT
        ['Sleep',7.28] // Tooltip says 7.3 - INCORRECT
    ]);
 
    var options = {
        title: 'My Daily Activities'
    };
 
    var chart = new google.charts.Bar(document.getElementById('chart_div'));
 
    chart.draw(data,google.charts.Bar.convertOptions(options));
}
