<h4>Plotting multi-series chart from data contained in Array.</h4>
<?php
	//In this example, we plot a multi series chart from data contained
	//in an array. The array will have three columns - first one for data label (product)
	//and the next two for data values. The first data value column would store sales information
	//for current year and the second one for previous year.
	
	//Let's store the sales data for 6 products in our array. We also store the name of products. 
	//Store Name of Products
	$arrData[0][1] = "Product A";
	$arrData[1][1] = "Product B";
	$arrData[2][1] = "Product C";
	$arrData[3][1] = "Product D";
	$arrData[4][1] = "Product E";
	$arrData[5][1] = "Product F";
	//Store sales data for current year
	$arrData[0][2] = 567500;
	$arrData[1][2] = 815300;
	$arrData[2][2] = 556800;
	$arrData[3][2] = 734500;
	$arrData[4][2] = 676800;
	$arrData[5][2] = 648500;
	//Store sales data for previous year
	$arrData[0][3] = 547300;
	$arrData[1][3] = 584500;
	$arrData[2][3] = 754000;
	$arrData[3][3] = 456300;
	$arrData[4][3] = 754500;
	$arrData[5][3] = 437600;

	//Now, we need to convert this data into multi-series XML. 
	//We convert using string concatenation.
	// $strXML - Stores the entire XML
	// $strCategories - Stores XML for the <categories> and child <category> elements
	// $strDataCurr - Stores XML for current year's sales
	// $strDataPrev - Stores XML for previous year's sales
	
	//Initialize <graph> element
	$strXML = "<graph caption='Sales by Product' numberPrefix='$' formatNumberScale='1' rotateValues='1' decimalPrecision='0' >";
	
	//Initialize <categories> element - necessary to generate a multi-series chart
	$strCategories = "<categories>";
	
	//Initiate <dataset> elements
	$strDataCurr = "<dataset seriesName='Current Year' color='AFD8F8'>";
	$strDataPrev = "<dataset seriesName='Previous Year' color='F6BD0F'>";
	
	//Iterate through the data  
	foreach ($arrData as $arSubData) {
        //Append <category name='...' /> to strCategories
        $strCategories .= "<category name='" . $arSubData[1] . "' />";
        //Add <set value='...' /> to both the datasets
        $strDataCurr .= "<set value='" . $arSubData[2] . "' />";
        $strDataPrev .= "<set value='" . $arSubData[3] . "' />";
	}
	
	//Close <categories> element
	$strCategories .= "</categories>";
	
	//Close <dataset> elements
	$strDataCurr .= "</dataset>";
	$strDataPrev .= "</dataset>";
	
	//Assemble the entire XML now
	$strXML .= $strCategories . $strDataCurr . $strDataPrev . "</graph>";
	
	//Create the chart - MS Column 3D Chart with data contained in strXML
	echo renderChart("../../FusionCharts/FCF_MSColumn3D.swf", "", $strXML, "productSales", 600, 300, false, false);
