Hi, i need a little bit of help here.
I'm creating a report form, which after showing some data in tables from the database lets you select different parameters to create a customized chart. You can even select the type of chart you want to display.
So far it's been successful creating pies and columns charts sorting the database with the parameters the user sends through the form but now i have to make comparative charts. The right option for that would be Multi-series Column 3D Charts to compare for example the sales of 2006 and 2007.
I have the example in the documentation but only the XML code and no PHP code, i don't see where i have to specify the type of chart and i don't know if i have to use
