Google Chart: Altering height of chart dynamically, based on total rows
提问by Hadleigh
Google have recently provided the ability to filter the graph results using some native controls.
Google 最近提供了使用一些本机控件过滤图形结果的功能。
Some of the code I provide below is taken directly from the new 'Dependent controls'in the Google Chart API playground. My problem is directly related to limitations imposed in this new dynamic functionality.
我在下面提供的一些代码直接取自Google Chart API 游乐场中的新“相关控件”。我的问题与此新动态功能中强加的限制直接相关。
I have a large dataset of 4000+ rows, which I want to display in one hbar graph. I don't know how many rows there will be but I can use the following code to find out.
我有一个包含 4000 多行的大型数据集，我想将其显示在一个 hbar 图中。我不知道会有多少行，但我可以使用以下代码来找出。
var initialHeight = data.getNumberOfRows() * 60
The problem I have is that the chart height needs to be very tall in order to display all of the 4000+ records. But the chart height does not change when the dependent controls are applied. Instead of resizing, the data 'grows' to fill the original graph height. The bars in the chart just become taller within the same space. Therefore, when my 4000+ records are filtered down to just one record, that one record is as tall as the initial 4000+.
我的问题是图表高度需要非常高才能显示所有 4000 多条记录。但是当应用相关控件时，图表高度不会改变。数据“增长”以填充原始图形高度，而不是调整大小。图表中的条形在同一空间内变得更高。因此，当我的 4000+ 条记录被过滤到只有一条记录时，那条记录与最初的 4000+ 条记录一样高。
To combat this I am using JQUERY to alter the size of the DIV surrounding the graph, which in turn alters the graph size. This works because the graph inherits its size from the surrounding DIV, if its not explicitly set.
为了解决这个问题，我使用 JQUERY 来改变图形周围 DIV 的大小，从而改变图形大小。这是有效的，因为图形从周围的 DIV 继承其大小，如果它没有明确设置。
** THE INITIAL RESPONSES BELOW REFERRED TO CODE I HAVE NOW REMOVED, BECAUSE THE DEVELOPMENT HAS PROGRESSED. **
** 下面的初始响应参考了我现在已删除的代码，因为开发已经取得进展。**
Part 2.
第2部分。
Following kind help from Oli, I have further developed this script and it is almost working ... I hope.
在Oli 的帮助下，我进一步开发了这个脚本，它几乎可以工作了......我希望。
There are two caviats to that statement.
该声明有两个注意事项。
The first is that it has to 'draw' the chart twice, the first time in order to calculate the number of rows it needs to display, the second time in order to stretch or shrink the size of the chart to the equally sized Div.
第一个是它必须“绘制”图表两次，第一次是为了计算它需要显示的行数，第二次是为了将图表的大小拉伸或缩小到相同大小的 Div。
This is not as concise as I would like it but can't find a way around it?
这不像我想要的那么简洁，但找不到解决方法？
The second caviat is that it errors on the 'ready' state of the first 'draw' event. If you remove the following code for the 3 'ControlWrapper' elements you will see them.
第二个缺点是它在第一个 'draw' 事件的 'ready' 状态上出错。如果您删除 3 个“ControlWrapper”元素的以下代码，您将看到它们。
if(barChart.getDataTable()){
This error means that altering the 'cityPicker' filter does not change the height. It now works for the country and region as it should do.
此错误意味着更改“cityPicker”过滤器不会更改高度。它现在适用于该国家和地区，因为它应该这样做。
Once again, I cannot find a way around this. and I think that it's my JS knowledge, rather than anything else.
再一次，我找不到解决方法。我认为这是我的 JS 知识，而不是其他任何东西。

A massive thanks in advance for any help you can provide in creating this script. I think it will be hugely useful.
非常感谢您在创建此脚本时提供的任何帮助。我认为这将非常有用。

This code is finally working in the example I provide below. The only thing it requires is the height of the surrounding DIV to be set at runtime. Maybe you can find a way around this.
这段代码终于在我下面提供的示例中起作用了。它唯一需要的是在运行时设置周围 DIV 的高度。也许你可以找到解决这个问题的方法。

From what I understand, you want to find out the number of rows in the underlying data table of a chart after a filter has been applied.
据我了解，您想找出应用过滤器后图表的基础数据表中的行数。
You could do this by adding event listeners to your controls, listening for a 'statechange' event. This is fired when a control changes. When this happens, you can grab your chart and get the updated number of rows in it's data table. Control docs here.
您可以通过向控件添加事件侦听器、侦听“statechange”事件来实现此目的。这是在控件更改时触发的。发生这种情况时，您可以抓取图表并获取其数据表中更新的行数。控制文档在这里。
I added the following just before the final closing brace in your linked example in the playground, give it a shot:
我在操场上的链接示例中的最后一个大括号之前添加了以下内容，试一试：
google.visualization.events.addListener(countryPicker, 'statechange', function() {
alert(barChart.getDataTable().getNumberOfRows());
});
Change the country picker and it should alert the updated number of rows.
更改国家/地区选择器，它应该提醒更新的行数。
