<h4>Plotting Stacked Chart from data contained in Array.</h4>
<?php
//In this example, we plot a Stacked chart from data contained
//in an array. The array will have three columns - first one for Quarter Name
//and the next two for data values. The first data value column would store sales information
//for Product A and the second one for Product B.
//Store Name of Products
$arrData[0][1] = "Quarter 1";
$arrData[1][1] = "Quarter 2";
$arrData[2][1] = "Quarter 3";
$arrData[3][1] = "Quarter 4";
// Sales data for Product A
$arrData[0][2] = 567500;
$arrData[1][2] = 815300;
$arrData[2][2] = 556800;
$arrData[3][2] = 734500;
// Sales data for Product B
$arrData[0][3] = 547300;
$arrData[1][3] = 594500;
$arrData[2][3] = 754000;
$arrData[3][3] = 456300;
//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
// $strDataProdA - Stores XML for current year's sales
// $strDataProdB - Stores XML for previous year's sales
//Initialize <graph> element
$strXML = "<graph caption='Sales' numberPrefix='$' formatNumberScale='0' decimalPrecision='0'>";
//Initialize <categories> element - necessary to generate a stacked chart
$strCategories = "<categories>";
//Initiate <dataset> elements
$strDataProdA = "<dataset seriesName='Product A' color='AFD8F8'>";
$strDataProdB = "<dataset seriesName='Product B' color='F6BD0F'>";
//Iterate through the data
foreach ($arrData as $arSubData) {
//Append <category name='...' /> to strCategories
$strCategories .= "<category name='" . $arSubData[1] . "' />";
//Add <set value='...' /> to both the datasets
$strDataProdA .= "<set value='" . $arSubData[2] . "' />";
$strDataProdB .= "<set value='" . $arSubData[3] . "' />";
}
//Close <categories> element
$strCategories .= "</categories>";
//Close <dataset> elements
$strDataProdA .= "</dataset>";
$strDataProdB .= "</dataset>";
//Assemble the entire XML now
$strXML = $strXML . $strCategories . $strDataProdA . $strDataProdB . "</graph>";
//Create the chart - Stacked Column 3D Chart with data contained in strXML
echo renderChart("../../FusionCharts/FCF_StackedColumn3D.swf", "", $strXML, "productSales", 600, 300);
