Hi, may I know can I show the value on the treemap? Just like a mouseover function on other google chart. Cos I saw on the sample at google playground, it only show the 'name' of that area instead of showing the 'value'. Can I know what is the coding?
Thank you.

If I recall correctly, the TreeMapCharts do not yet support adding values to the tooltips, nor do they support custom tooltips. You can create your own tooltips by registering "onmouseover" and "onmouseout" event handlers for the chart (these events pass an object containing the row of the DataTable that the moused over element is in; you can use this information to fetch data and populate your tooltip). Here's an example to get you started: http://jsfiddle.net/asgallant/fR7a9/ (note this example uses the jQuery library to assist with the tooltip; you can do it all without jQuery if you don't use the library)..

Hi,I have copy all the coding and create a new HTML file but I don know why the mouseover function on the treemap is not working like the 'Result'. I upload the file and can you help me to check where is the error?

That example code uses jQuery to create the tooltips; if you want to use the code as-is, you need to add a script tag for jQuery, like this:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>

Are you running this from your local machine or a webserver? If it's your local machine, you need to add "http:" to the jQuery script's url.
