在php中使用FusionCharts
作者:zccst

数据格式有setDataURL(srcUrl)和setJSONData(jsonStr)两种
用法在官方demo和document都有详细解释。
在实际需求中,直接参考官方资料还是挺方便的。


fileUrl = '../path/to/xx.swf';  //swf文件路径 
srcUrl  = 'http://url?a=1&b=2'; //向后端请求的url。

一、setDataURL(srcUrl)方式

//前端:<div id="outsource_sta_1"></div>var myChart = new FusionCharts(fileUrl, "myChartId", "600", "500");myChart.setDataURL(srcUrl);myChart.render("outsource_sta_1");//后端:$xml = "<chart palette=\"2\" caption=\"平均处理时间统计\" xAxisName=\"机型\" yAxisName=\"平均处理时间\" showValues=\"1\" decimals=\"2\" formatNumberScale=\"0\" useRoundEdges=\"1\" showPercentValues='1' >";for($i = 1; $i < 6; $i++){    $data[] = array('label'=>'m'.$i, 'value'=>$i);    $xml .= "<set label=\"'m'.$i\" value=\"$i\" />";}$xml .= "</chart>";print $xml;

批注1:本质是data.xml,可以直接丢一个data.xml格式的文件,也可以是一个url,该url的返回值是xml格式的数据。
批注2:有可能乱码。在yii中使用会乱码。但在extjs中没有。


二、setJSONData(jsonStr)
又分两种情况:
第一种情况是new FusionCharts(...)在前端,仅jsonStr从后端获取
例如:
//前端:<div id="outsource_sta_1"></div>$.post(srcUrl,null,function(r){    var myChart = new FusionCharts(fileUrl, "myChartId", "600", "500");    myChart.setJSONData(r);    myChart.render("outsource_sta_1");},'json');//后端:$data = array();for($i = 1; $i < 6; $i++){    $data[] = array('label'=>'m'.$i, 'value'=>$i);}$chart = array();$chart['palette'] = 2;$chart['caption'] = "平均处理时间统计";$chart['xAxisName'] = "机型";$chart['yAxisName'] = "平均处理时间";$chart['showValues'] = 1;$chart['decimals'] = 2;$chart['formatNumberScale'] = 0;$chart['useRoundEdges'] = 1;$chart['showPercentValues'] = 1;$ret = array('chart'=>$chart,'data'=>$data);print json_encode($ret);

批注:$.post()的返回值是'json'类型。


第二种情况是所有都在后端,前端直接$(".outsource_content").html(r)
//前端:<div id="outsource_sta_1"></div>$.post(srcUrl,null,function(r){    $(".outsource_content").html(r);},'html');//后端:$data = array();for($i = 1; $i < 6; $i++){    $data[] = array('label'=>'m'.$i, 'value'=>$i);}$chart = array();$chart['palette'] = 2;$chart['caption'] = "平均处理时间统计";$chart['xAxisName'] = "机型";$chart['yAxisName'] = "平均处理时间";$chart['showValues'] = 1;$chart['decimals'] = 2;$chart['formatNumberScale'] = 0;$chart['useRoundEdges'] = 1;$chart['showPercentValues'] = 1;$ret = array('chart'=>$chart,'data'=>$data);$ret = json_encode($ret);$ret = self::generateChart('Column2D',$ret, 600,500, 'myid1', 'outsource_sta_1');$ret = self::wrapScript($ret);print $ret;public static function wrapScript($scripts){    $html = '<script type="text/javascript">';    $html.= "\n";    $html.= $scripts;    $html.= "\n";    $html.= "</script>";    return $html;}public static function generateChart($type, $data, $width=0, $height=0, $myid='', $div_id=''){    if(!$type || !$data){        return '';    }    $width = intval($width)?intval($width):800;    $height = intval($height)?intval($height):400;    $width = $width<600?600:$width;    $height = $height<400?400:$height;    $url = Yii::app()->baseUrl . "/resources/fusion/{$type}.swf";    $mychartid = $myid . 'a';    $script = <<<JAVASCRIPTvar {$myid} = new FusionCharts('{$url}','{$mychartid}', '{$width}','{$height}');{$myid}.setJSONData('{$data}');{$myid}.render('{$div_id}');JAVASCRIPT;    return $script;}

批注1:$.post()的返回值是'html'类型。也可以测试其他类型是否可以正常显示。
但是不能是json格式。其本质是一些已经组建好的javascript,添加到制定div后就立即执行了。

批注2:针对第二种情况,也可以显示两个图表,(当然也可以显示多个)



后端在添加:
$ret2 = $ret;$ret2 = self::generateChart('Column2D', $ret2, 600,500,'myid2','outsource_sta_2');$ret2 = self::wrapScript($ret2);print $ret.$ret2;



三、setJSONData()的高级形式
高级的原因是:后端不只是传来渲染图表(fusionCharts)的完整js,还包括其他值,此时$.post()的返回值是'json'类型。
//前端:$.post(srcUrl,null,function(r){    console.log(r.v);    $(".outsource_content").html(r.g);},'json');//后端://在上面的基础上$return = array('v'=>100,'g'=>$ret.$ret2);

批注1:100的位置可以放置任意负责的数据,而且还可以v1,v2等等。

批注2:此时$.post()的返回值是'json'类型。这个必须强调。

How to calculate the total number of elements in a PHP multidimensional array?How to calculate the total number of elements in a PHP multidimensional array?May 15, 2025 pm 09:00 PM

Calculating the total number of elements in a PHP multidimensional array can be done using recursive or iterative methods. 1. The recursive method counts by traversing the array and recursively processing nested arrays. 2. The iterative method uses the stack to simulate recursion to avoid depth problems. 3. The array_walk_recursive function can also be implemented, but it requires manual counting.

What are the characteristics of do-while loops in PHP?What are the characteristics of do-while loops in PHP?May 15, 2025 pm 08:57 PM

In PHP, the characteristic of a do-while loop is to ensure that the loop body is executed at least once, and then decide whether to continue the loop based on the conditions. 1) It executes the loop body before conditional checking, suitable for scenarios where operations need to be performed at least once, such as user input verification and menu systems. 2) However, the syntax of the do-while loop can cause confusion among newbies and may add unnecessary performance overhead.

How to hash strings in PHP?How to hash strings in PHP?May 15, 2025 pm 08:54 PM

Efficient hashing strings in PHP can use the following methods: 1. Use the md5 function for fast hashing, but is not suitable for password storage. 2. Use the sha256 function to improve security. 3. Use the password_hash function to process passwords to provide the highest security and convenience.

How to implement array sliding window in PHP?How to implement array sliding window in PHP?May 15, 2025 pm 08:51 PM

Implementing an array sliding window in PHP can be done by functions slideWindow and slideWindowAverage. 1. Use the slideWindow function to split an array into a fixed-size subarray. 2. Use the slideWindowAverage function to calculate the average value in each window. 3. For real-time data streams, asynchronous processing and outlier detection can be used using ReactPHP.

How to use the __clone method in PHP?How to use the __clone method in PHP?May 15, 2025 pm 08:48 PM

The __clone method in PHP is used to perform custom operations when object cloning. When cloning an object using the clone keyword, if the object has a __clone method, the method will be automatically called, allowing customized processing during the cloning process, such as resetting the reference type attribute to ensure the independence of the cloned object.

How to use goto statements in PHP?How to use goto statements in PHP?May 15, 2025 pm 08:45 PM

In PHP, goto statements are used to unconditionally jump to specific tags in the program. 1) It can simplify the processing of complex nested loops or conditional statements, but 2) Using goto may make the code difficult to understand and maintain, and 3) It is recommended to give priority to the use of structured control statements. Overall, goto should be used with caution and best practices are followed to ensure the readability and maintainability of the code.

How to implement data statistics in PHP?How to implement data statistics in PHP?May 15, 2025 pm 08:42 PM

In PHP, data statistics can be achieved by using built-in functions, custom functions, and third-party libraries. 1) Use built-in functions such as array_sum() and count() to perform basic statistics. 2) Write custom functions to calculate complex statistics such as medians. 3) Use the PHP-ML library to perform advanced statistical analysis. Through these methods, data statistics can be performed efficiently.
