To specify the database connection parameters you need an 8-slot associative array with the following keys defined:

- DB_Type: the name of the database server (mysql,pgsql etc)
- DB_Username: the database username
- DB_Passwd: the database user password
- DB_Host: the DNS name or ip number of the database server
- DB_Name: the name of the database
- Field_GroupName: the name of the table field holding the group name
- Field_ItemName: the name of the table field holding the item name of the above group
- Field_ItemValue: the name of the table field holding the item value

The SQL query can be specified with a one-slot associative array:
array("Query"=>"SELECT * FROM my_table")

To make things clear let's see an example:
Suppose you have the following database table and want to graph its contents:

In this case to generate the chart properly you have to specify the following attributes:

include("../Sources/phpchartPlus.php");
include("../Sources/CacheToFile_Strategy.php");
include("../Sources/PEARDBData_Strategy.php");
include("../Sources/XMLConfig_Strategy.php");
	
$DataParams=array("DB_Type"=>"",
                  "DB_Username"=>"",
                  "DB_Passwd"=>"",
                  "DB_Host"=>"",
                  "DB_Name"=>"",
                  "Field_GroupName"=>"",
                  "Field_ItemName"=>"",
                  "Field_ItemValue"=>"");
				    
$ConfigParams=array("filename"=>"../Data/phpchartplus.conf.xml");
	
$DataStrategy=new PEARDBData_Strategy();
$ConfigStrategy=new XMLConfig_Strategy();
$CacheStrategy=new CacheToFile_Strategy();

$im=new phpchartPlus();
                   
try
{
$im->DataParser_->strategize($DataStrategy,$DataParams);
$im->DataParser_->parse(array("Query"=>"SELECT * FROM my_table"));
}
   catch (DataParser_Exception $e) 
   {
     print $e->getMessage();
     exit();
   }
   catch (DataStrategy_Exception $f) 
   {
     print $f->getMessage();
     exit();
   }
   
try
{
$im->ConfigParser_->strategize($ConfigStrategy,$ConfigParams);
$im->ConfigParser_->parse();
}
   catch (ConfigParser_Exception $e) 
   {
     print $e->getMessage();
     exit();
   }
   catch (ConfigStrategy_Exception $f) 
   {
     print $f->getMessage();
     exit();
   } 
   
try
{
$im->get_Instance();
}
   catch (ImageSupport_Exception $e)
   {
     print $e->getMessage();
     exit();
   }
   catch (FontSupport_Exception $f)
   {
     print $f->getMessage();
     exit();
   }
   
$im->Chart_->set_CachingStrategy($CacheStrategy,2); 
//Cache for 2 minutes 
$im->Chart_->draw_Chart();
