请参阅此问题图表。我不能张贴图表:
Google Pie Charts Label
我必须获取饼图中单击的切片的 ID 并使用其 ID 并将其与 url 连接以使其可重定向。使用点击切片的 id 作为查询字符串。请帮忙。
最佳答案
您需要从DataTable中获取相关数据:
function selectHandler() {
var selection = chart.getSelection();
if (selection.length) {
var pieSliceLabel = data.getValue(selection[0].row, 0);
window.location.href = 'http://www.google.com?search=' + pieSliceLabel;
}
}
关于javascript - 使用 Google-charts api 中的饼图切片将切片点击导航到不同的页面，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/22150329/
