FusionCharts是一套很有用的统计图生成工具,本文主要介绍一下FusionCharts大概的执行流程:

1.我们先从数据库取数据;

2.用php代码做一个生成xml的函数,把数据生成xml;

3.用一段js读取xml,送到FusionCharts,生成统计图表。

说起来还是挺烦琐的,所以还是开始做吧。这里要做两个函数,makexml(),render(),方便我们的调用。

view plaincopy to clipboardprint?
function makexml($data)   
{   
    $strXML .= "";   
    foreach ($data as $k=>$v)   
    {   
        $strXML .= "<set name='".$v['Option']."' value='".$v['Num']."' />"; //省掉了color   
    }   
    return $strXML;   
}  
function makexml($data)
{
    $strXML .= "";
    foreach ($data as $k=>$v)
    {
        $strXML .= "<set name='".$v['Option']."' value='".$v['Num']."' />"; //省掉了color
    }
    return $strXML;
} 

注意!FusionCharts根据生成统计表的不同分了两种xml格式,如下所示,大家可以参考Gallery/Data文件夹里面。可能我说漏了也说不定。所以上面那个函数是对应生成第一种。

view plaincopy to clipboardprint?
<graph caption='Monthly Unit Sales' xAxisName='Month' yAxisName='Units' decimalPrecision='0' formatNumberScale='0' chartRightMargin='30'>  
<set name='Jan' value='462' color='AFD8F8' />  
<set name='Feb' value='857' color='F6BD0F' />  
<set name='Mar' value='671' color='8BBA00' />  
<set name='Apr' value='494' color='FF8E46'/>  
<set name='May' value='761' color='008E8E'/>  
</graph>  
<graph caption='Monthly Unit Sales' xAxisName='Month' yAxisName='Units' decimalPrecision='0' formatNumberScale='0' chartRightMargin='30'>

<set name='Mar' value='671' color='8BBA00' />
<set name='Apr' value='494' color='FF8E46'/>
<set name='May' value='761' color='008E8E'/>
</graph>

      <set value='28' />
      <set value='26' />
      <set value='10' />
   </dataset>
</graph>

接下来是render()函数

view plaincopy to clipboardprint?
function render($caption, $XAxisName, $chartSWF, $XML, $chartId='char', $chartWidth=265, $chartHeight=200, $debugMode=false, $registerWithJS=true)   
{   
    //animation=1: 开启flash,0:关闭flash效果 caption:表头标题 XAxisName:x轴标题 decimalPrecision:坐标显示小数位数 baseFontSize:字体大小 formatNumberScale:格式化坐标 numberPrefix:在数值前面加符号 showValues:显示数值   
    $strXML  = "<graph caption='$caption' XAxisName='$XAxisName' palette='2' decimalPrecision='0' baseFontSize='12' animation='1' formatNumberScale='1' numberPrefix='' showValues='0' >";   
    $strXML .= $XML;   
    $strXML .= "</graph>";   
    $tempData = "//Provide entire XML data using dataXML methodnttchart_$chartId.setDataXML("$strXML");";   
    
    // Set up necessary variables for the RENDERCAHRT   
    $chartIdDiv = $chartId . "Div";   
    $ndebugMode = boolToNum($debugMode);   
    $nregisterWithJS = boolToNum($registerWithJS);   
    
    // create a string for outputting by the caller   
    $render_chart = "   
    
        <!-- START Script Block for Chart $chartId -->   
        <div id='$chartIdDiv' align='center'>   
            Chart.   
        </div>   
        <mce:script type="text/javascript"><!--   
    
            //Instantiate the Chart    
            var chart_$chartId = new FusionCharts("Charts/$chartSWF", "$chartId", "$chartWidth", "$chartHeight", "$ndebugMode", "$nregisterWithJS");   
            $tempData  
            //Finally, render the chart.   
            chart_$chartId.render("$chartIdDiv");   
           
// --></mce:script>      
        <!-- END Script Block for Chart $chartId -->";   
    
    return $render_chart;   
}  
function render($caption, $XAxisName, $chartSWF, $XML, $chartId='char', $chartWidth=265, $chartHeight=200, $debugMode=false, $registerWithJS=true)
{
    //animation=1: 开启flash,0:关闭flash效果 caption:表头标题 XAxisName:x轴标题 decimalPrecision:坐标显示小数位数 baseFontSize:字体大小 formatNumberScale:格式化坐标 numberPrefix:在数值前面加符号 showValues:显示数值
    $strXML  = "<graph caption='$caption' XAxisName='$XAxisName' palette='2' decimalPrecision='0' baseFontSize='12' animation='1' formatNumberScale='1' numberPrefix='' showValues='0' >";
    $strXML .= $XML;
    $strXML .= "</graph>";
    $tempData = "//Provide entire XML data using dataXML methodnttchart_$chartId.setDataXML("$strXML");";
 
    // Set up necessary variables for the RENDERCAHRT
    $chartIdDiv = $chartId . "Div";
    $ndebugMode = boolToNum($debugMode);
    $nregisterWithJS = boolToNum($registerWithJS);
 
    // create a string for outputting by the caller
    $render_chart = "
 
        <!-- START Script Block for Chart $chartId -->
        <div id='$chartIdDiv' align='center'>
            Chart.
        </div>
        <mce:script type="text/javascript"><!--
 
            //Instantiate the Chart 
            var chart_$chartId = new FusionCharts("Charts/$chartSWF", "$chartId", "$chartWidth", "$chartHeight", "$ndebugMode", "$nregisterWithJS");
            $tempData
            //Finally, render the chart.
            chart_$chartId.render("$chartIdDiv");
        
// --></mce:script>   
        <!-- END Script Block for Chart $chartId -->";
 
    return $render_chart;
}

接下来就到了调用过程,简单的几句话,假设数据放在result数组里。

view plaincopy to clipboardprint?
foreach ($results as $key => $value) {   
        $arr[] = array('Option'=>$value['name'],'Num'=>$value['num']);    
    }   
    $xml = makexml($arr);   
    $fusionchart = 'Pie3D.swf';   
    $output = render($title,'',$fusionchart,$xml,$id);//每个图的id要不一样的,一样的话就。。。  
foreach ($results as $key => $value) {
        $arr[] = array('Option'=>$value['name'],'Num'=>$value['num']); 
    }
    $xml = makexml($arr);
    $fusionchart = 'Pie3D.swf';
    $output = render($title,'',$fusionchart,$xml,$id);//每个图的id要不一样的,一样的话就。。。

最后在html加入js文件调用代码,把output打印出来就搞定了~

view plaincopy to clipboardprint?
<mce:script type="text/javascript" src="tool/admin/vendors/FusionCharts/FusionCharts.js" mce_src="tool/admin/vendors/FusionCharts/FusionCharts.js"></mce:script>  
<?php echo $output ?>  
<mce:script type="text/javascript" src="tool/admin/vendors/FusionCharts/FusionCharts.js" mce_src="tool/admin/vendors/FusionCharts/FusionCharts.js"></mce:script>
<?php echo $output ?>
