我需要在一个网页中创建多个图表，每个图表的数据都来自一个 MySql 数据库，但来自不同的表。我需要在同一网页中显示多个图表。目前我为此目的使用以下代码

我使用融合图作为制图工具

将显示图表的页面

<?php
include("Includes/FusionCharts.php");
 include("Includes/DBConn.php");
?>
<HTML>
<HEAD>
<TITLE>
FusionCharts Free - Database Example
</TITLE>
<?php
?>  
<SCRIPT LANGUAGE="Javascript" SRC="FusionCharts/FusionCharts.js"></SCRIPT>
<style type="text/css">
<!--
body {
    font-family: Arial, Helvetica, sans-serif;
    font-size: 12px;
}
.text{
    font-family: Arial, Helvetica, sans-serif;
    font-size: 12px;
}
-->
</style>
</HEAD>
<BODY>

<table width="402" border="3" cellpadding="0">
 <tr>
<td width="390" height="63" align="left"><?php

$link = connectToDB();

    $strXML = "<graph caption='Factory Output report' subCaption='By Quantity' pieSliceDepth='30' showBorder='1' showNames='1' formatNumberScale='0' numberSuffix=' Units' decimalPrecision='0'>";


$strQuery = "select * from top_buy_traders";
$result = mysql_query($strQuery) or die(mysql_error());


if ($result) {
    while($ors = mysql_fetch_array($result)) {

        $strQuery = "select sum(qty) as TotOutput from top_buy_traders where id=" . $ors['id'];
        $result2 = mysql_query($strQuery) or die(mysql_error()); 
        $ors2 = mysql_fetch_array($result2);
        //Generate <set name='..' value='..' />        
        $strXML .= "<set name='" . $ors['buy_trader'] . "' value='" .    $ors2['TotOutput'] . "' />";
        //free the resultset
        mysql_free_result($result2);
    }
}
mysql_close($link);

//Finally, close <graph> element
$strXML .= "</graph>";

//Create the chart - Pie 3D Chart with data from $strXML
echo renderChart("FusionCharts/FCF_Pie3D.swf", "", $strXML, "FactorySum", 325,  225);
  ?></td>

   </tr>
 </table>
</BODY>
</HTML>

Fusion Chart.php如下

<?php

function encodeDataURL($strDataURL, $addNoCacheStr=false) {

if ($addNoCacheStr==true) {
        if (strpos($strDataURL,"?")<>0)
        $strDataURL .= "&FCCurrTime=" . Date("H_i_s");
    else
        $strDataURL .= "?FCCurrTime=" . Date("H_i_s");
}
return urlencode($strDataURL);
}


 function datePart($mask, $dateTimeStr) {
@list($datePt, $timePt) = explode(" ", $dateTimeStr);
$arDatePt = explode("-", $datePt);
$dataStr = "";
    if (count($arDatePt) == 3) {
    list($year, $month, $day) = $arDatePt;

    switch ($mask) {
    case "m": return $month;
    case "d": return $day;
    case "y": return $year;
    }

    return (trim($month . "/" . $day . "/" . $year));
}
return $dataStr;
 }


function renderChart($chartSWF, $strURL, $strXML, $chartId, $chartWidth, $chartHeight, $debugMode=false, $registerWithJS=false, $setTransparent="") {
//First we create a new DIV for each chart. We specify the name of DIV as "chartId"Div.         

if ($strXML=="")
    $tempData = "//Set the dataURL of the chart\n\t\tchart_$chartId.setDataURL(\"$strURL\")";
else
    $tempData = "//Provide entire XML data using dataXML method\n\t\tchart_$chartId.setDataXML(\"$strXML\")";

// Set up necessary variables for the RENDERCAHRT
$chartIdDiv = $chartId . "Div";
$ndebugMode = boolToNum($debugMode);
$nregisterWithJS = boolToNum($registerWithJS);
$nsetTransparent=($setTransparent?"true":"false");



$render_chart = <<<RENDERCHART

<!-- START Script Block for Chart $chartId -->
<div id="$chartIdDiv" align="center">
    Chart.
</div>
<script type="text/javascript"> 
    //Instantiate the Chart 
    var chart_$chartId = new FusionCharts("$chartSWF", "$chartId", "$chartWidth", "$chartHeight", "$ndebugMode", "$nregisterWithJS");
  chart_$chartId.setTransparent("$nsetTransparent");

    $tempData

    chart_$chartId.render("$chartIdDiv");
</script>   
<!-- END Script Block for Chart $chartId -->
RENDERCHART;

  return $render_chart;
}

DBConn.php如下

<?php
 function connectToDB() {



  $hostdb = 'localhost'; // MySQl host
  $userdb = 'root';  // MySQL username
  $passdb = '';  // MySQL password
  $namedb = 'phptest'; // MySQL database name


  $link = mysql_connect ("localhost:3306", "root", "");

   if (!$link) {
    die('Could not connect: ' . mysql_error());    }



    $db_selected = mysql_select_db($namedb);
    if (!$db_selected) {
    die ('Can\'t use database : ' . mysql_error());
    }
    return $link;
  }
 ?>

















  function renderChartHTML($chartSWF, $strURL, $strXML, $chartId, $chartWidth,  $chartHeight, $debugMode=false,$registerWithJS=false, $setTransparent="") {
    $strFlashVars = "&chartWidth=" . $chartWidth . "&chartHeight=" . $chartHeight . "&debugMode=" . boolToNum($debugMode);
if ($strXML=="")

    $strFlashVars .= "&dataURL=" . $strURL;
else

    $strFlashVars .= "&dataXML=" . $strXML;

  $nregisterWithJS = boolToNum($registerWithJS);
  if($setTransparent!=""){
    $nsetTransparent=($setTransparent==false?"opaque":"transparent");
  }else{
  $nsetTransparent="window";
  }
 $HTML_chart = <<<HTMLCHART
<!-- START Code Block for Chart $chartId -->
<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=8,0,0,0" width="$chartWidth" height="$chartHeight" id="$chartId">

    <param name="movie" value="$chartSWF"/>

    <param name="quality" value="high" />
    <param name="wmode" value="$nsetTransparent" />
    <embed src="$chartSWF" FlashVars="$strFlashVars&registerWithJS=$nregisterWithJS" quality="high" width="$chartWidth" height="$chartHeight" name="$chartId" allowScriptAccess="always" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" wmode="$nsetTransparent" />


</object>
<!-- END Code Block for Chart $chartId -->
HTMLCHART;

 return $HTML_chart; 
}

function boolToNum($bVal) {
return (($bVal==true) ? 1 : 0);
}

?>

最佳答案

每个图表都需要为其指定不同的 ID 和 DIV ID。在下面的行中，FactorySum 是您的图表 ID - 因此请为每个图表更改它。

echo renderChart("FusionCharts/FCF_Pie3D.swf", "", $strXML, "FactorySum", 325,  225);
