multi row header on Google Visualizations
- by Elzo Valugi
Hi, 
I am trying to create a DataTable with a multi row header. I'll exemplify here:
|               2008           |           2009          |
---------------------------------------------------------
|    price      |   qty.       |    price    |   qty     |
---------------------------------------------------------
|     93993     |  34434       |     34244   |   3434    |
.....
The years headers can be fixed as I don't want to do sorting by that.
Is there a way to do that in Google Visualizations?
