All,

I need to make a bar chart that has data grouped within each series, so that each "bar" in the chart is combination of multiple data points.  I am able to do this using Google Charts, but providing the information with a clean legend is problematic, so I am investigating the use of Google Visualizations.

An example of the type of the Google Chart, without legends for the subdata making up the bars:

I stumbled upon the codeshare library for Google Visualizations (http://wiki.developerforce.com/index.php/Google_Visualizations).

I was wondering if anyone had used the ColumnChart component and related code to create this type of Chart?  It looks possible, just wanted a quick sanity check before I invest in a lot of time on it.

Thanks,

David
