如何从Google Chart API获取条形名称 [英] How to get the bar names from Google Chart api

问题描述

我被困了几天！
我制作了一个应用来显示猫的品种以及何时在欧洲发现它们.

这是我的代码:

由于论坛想要重新格式化，因此我无法在此处发布我的代码.
检查我的Google云端硬盘:
我的代码

我想做的就是获取时间轴栏中的名称.例如，如果我单击"pers(ion)"，我想动态地使div包含有关pers(ion)的更多信息.但是因为它没有类或ID，所以我无法获得它.

现在有人容易做到这一点吗?

解决方案

这将帮助您获取BAR的名称.如果您的数据是

  var data = new google.visualization.arrayToDataTable([['Object'，'Count']，["ApexClass"，apexCount]，["Sobjects"，objectCount]，["ApexPage"，vfPageCount]，[角色"，rolesCount]，["Dashboard"，dashboardCount]，[个人资料"，profileCount]]); 

然后在选择处理程序中将其写入

  google.visualization.events.addListener(barchart，'select'，countsChartSelectListener);函数countsChartSelectListener(){var selectedItem = barchart.getSelection()[0];如果(selectedItem){var barName = data.getValue(selectedItem.row，0); 

I am stuck for a couple of days!
I making an app that show cat breeds and when they are discovered in europe.

This is my code:

Since I can't post my code here because the forum want to reformat it.
Check my Google drive:
My code
https://docs.google.com/document/d/1wiwgFI3tGimvXKzOinLUZMYXAaMVscECeQopiyEHB98/edit?usp=sharing

And It returns a good looking chart that looks like this:

What I trying to do is getting the name that's inside a bar of the timeline. As an example, if I click on "pers(ion)" , I want to make dynamicaly a div with more information about the pers(ion). But because it doesn't get a class or id I can't get it.

Does anybody now an easy way do do this?

解决方案

This will help you get the name of the BAR. If you data is

var data = new google.visualization.arrayToDataTable([
    ['Object', 'Count'],
    ["ApexClass", apexCount],
    ["Sobjects", objectCount],
    ["ApexPage", vfPageCount],
    ["Role", rolesCount],
    ["Dashboard", dashboardCount],
    ["Profile", profileCount]

    ]);

Then in select Handler write this

google.visualization.events.addListener(barchart, 'select', countsChartSelectListener);
    function countsChartSelectListener(){
        var selectedItem = barchart.getSelection()[0];
        if (selectedItem) {
            var barName = data.getValue(selectedItem.row, 0);
