我有一个谷歌条形图,其中包含我想要动态添加课程的条形标签。但是,我还没有找到一种方法来引用标签本身或添加课程。该图表是根据我正在构建的Google数据表创建的。
这是我想要完成的事情:
我觉得这应该很简单,但我还没有在文档中找到任何内容。有人有答案吗?
答案 0 :(得分:2)
标签是svg <text>
元素,由图表
您可以将css应用于所有<text>
元素,
但这不仅包括您指定的标签
相反,建议使用以下图表选项来设置标签样式...
hAxis: {
textStyle: {
color: <string>,
fontName: <string>,
fontSize: <number>,
bold: <boolean>,
italic: <boolean>
}
},
虽然不推荐,但您可以手动更改svg,
在图表的'ready'
或'animationfinish'
事件触发后
请参阅以下工作代码段...
google.charts.load('current', {
packages: ['corechart']
}).then(function () {
var data = google.visualization.arrayToDataTable([
['x', 'y'],
['RNI', 97],
['LDA', 100]
]);
var options = {
width: "100%",
legend: 'none',
backgroundColor: { fill: 'transparent' },
chartArea: { width: '80%' },
bar: { groupWidth: "50%" },
animation: { "startup": true, duration: 1000, easing: 'in' },
colors: ['#529736', '#007DB9', '#EC1C24'],
fontSize: 10,
hAxis: {
direction: 1,
title: 'Database'
},
vAxis: {
title: 'Percent Of Successful Intervals',
minValue: 75,
format: '#',
ticks: [75, 80, 85, 90, 95, 100]
}
};
var chart = new google.visualization.ColumnChart(document.getElementById('chart_div'));
google.visualization.events.addListener(chart, 'animationfinish', function () {
$($('text').filter(':contains("RNI")')[0]).attr('fill', '#ff0000');
$($('text').filter(':contains("RNI")')[0]).attr('font-size', '20');
});
chart.draw(data, options);
});

使用方法getImageURI
获取图表的图像时...
