使用 Google Visualization API 将条形图叠加到折线图之上
你好
有谁知道是否可以使用 Google Visualization API （在 Java 程序中）来绘制由叠加在折线图之上的条形图组成的图表。您可能会问为什么有人想要这样做？好吧，我想绘制一些日内交易信号。我目前正在使用 JFreechart 来绘制交易信号，但它没有很好的记录，这意味着您当你尝试做任何偏离常规的事情时，你只能靠自己。
提前致谢

Hello
Does anyone know if it's possible to use the Google Visualisation API (in a Java program) to plot a graph consisting of a bar chart overlayed on top of a Line chart. Why would anyone want to do this you might ask? Well, I have some day trading signals I would like to plot. I'm currently using JFreechart to plot trading signals but it's not very well documented which kinda means you're on your own when you try to do anything that strays from the beaten path.
Thanks in advance
PS: Sorry if my site is slow for you but this is due to the fact that it's hosted on an Amazon EC2 Micro Instance which gets severely throttled whenever traffic spikes (read Google crawls the pages) occur. Please be patient when you click on the link the chart will load.... eventually 10 seconds

谷歌图像图表工具可以做到这一点，但它将是一个静态图表（没有交互式数据点）。
试试这个：
这里：

有很多文档，您应该能够以任何语言生成所需的 URL。

我错了；看起来 组合图表 最近已添加到 js API 。这能满足您的需要吗？
Google image chart tools can do this, but it will be a static chart (no interactive data points).
Try this:
here:
http://code.google.com/apis/chart/image/docs/chart_playground.html
There are a bunch of docs, and you should be able to generate the required URL in any language.
UPDATE:
I was incorrect; looks like Combo Chart was recently added to the js API. Does this do what you need?
