{
Global $ flash_chart;
$ This-> id = $ id;
$ This-> height = $ height;
$ This-> width = $ width;
$ This-> path = $ path;
If (! $ Flash_chart)

Unset ($ this-> id, $ this-> height, $ this-> width, $ this-> path );
}
Function setID ($ id)
{
$ This-> id = $ id;
}
Function setChart ($ file, $ info)
{
$ Tp = new TemplateData ($ file );
Echo '<script type = "text/javascript"> ';
Echo "data _ {$ this-> id} =". $ tp-> changeInfo ($ info ).';';
Echo "function ofc_get_dataOf {$ this-> id} () {return JSON. stringify (data _ {$ this-> id });}";
Echo "swfobject. embedSWF ('". $ this-> path. "/open-flash-chart.swf ',' $ this-> id', '$ this-> width',' $ this-> height', '9.0.0', 'expressinstall.swf ', {'get-data ': 'oss _ get_dataOf {$ this-> id }'})";
Echo '</script> ';

3. TemplateData class

Extract the configuration of a simple icon from the txt text that has been written to load the class used: for exampleCopy codeThe Code is as follows :{
"Title ":
{
"Text": "(title )",
"Style": "{color: # FF0000; font-size: 24px ;}"
},
"Y_legend ":{
"Text": "iWebShop ",
"Style": "{color: # 736AFF; font-size: 16px ;}"
},

"Elements ":[
{
"Type": "line ",
"Color": "# 736AFF ",
"Text": "Number of registered users (persons )",
"Width": 1,
"Dot-style ":{
"Type": "solid-dot", "color": "# a44a80", "dot-size": 3,
"Tip": "# val # Persons <br> # x_label #"},
"On-show": {"type": "shrink-in", "cascade": 1, "delay": 0.5 },
"Values": [(numbers)]
}
],

"X_axis ":{
"Labels ":{
"Labels": [(dates)]
}
},

"Y_axis ":{
"Steps": (steps ),
"Max": (max)
}
}

This is the content of the class:Copy codeThe Code is as follows:

Class TemplateData
{
Public $ substitution;
Private $ templateFile;
Function _ construct ($ filename)
{
$ This-> templateFile = @ file_get_contents ($ filename) or die ("not find templateFile ");
}
Function _ destruct (){
Unset ($ this-> templateFile, $ this-> substitution );
}
Function setTemplateFile ($ tfile)
{
$ This-> templateFile = $ tfile;
}
Function getTemplateFile ()
{
Return $ this-> templateFile;
}
Function replaceReal ($ matches)
{
Extract ($ this-> substitution, EXTR_OVERWRITE );
Return isset ($ matches [1])? $ Matches [1]: $ matches [1];
}
Function changeInfo ($ subs)
{
$ This-> substitution = $ subs;
Return preg_replace_callback ("(\ w +) \)", array (& $ this, 'replacereal'), $ this-> getTemplateFile ());
}

}

4. Called codeCopy codeThe Code is as follows:

<! -- // Here, myChat is the place where flash is displayed, so it cannot be blank. If it is changed, it should be defined when the FlashChart class is declared. For details, see the FlashChart class -->
<Div class = 'content _ box'> <div id = "myChart"> </div>

<? Php
Include ("flashchart. php ");
Include ("templatedata. php ");
$ Fc = new FlashChart ('chart/', "100%", 320 );
$ Infos = array (
'Numbers '=> "700 ",
'Dates' => "\" string 1 \ ", \" string 2 \ ", \" string 3 \ ", \" string 4 \", \ "string 5 \"",
'Steps' => 600000,
'Max '=> 6000000
);
$ Info = array ("title" => 'user registration statistics', 'numbers '=> $ infos ['numbers'], 'dates' => $ infos ['dates'], 'steps' => $ infos ['steps'], 'max '=> $ infos ['max']);
$ Fc-> setChart ("chart/templatechart/user-add.txt", $ info );

5. There is also a data processing function that converts the queried dataset into ofc data.

Copy codeThe Code is as follows:

/**
* @ Brief ofc Data Processing
* @ Params database query a dataset with data off x and Y axes
* @ Note background
*/
/*
Public function init_count ($ rs)
{

$ Numbers = '';
$ Dates = '';
$ Max = 0;
Foreach ($ rs as $ row)
{

$ Numbers. = $ row ['num']. ','; // y axis data
$ Dates. = '"'. $ row ['month']. '",'; // X axis data
If ($ max <$ row ['num']) $ max = $ row ['num'];
}
$ Steps = ceil ($ max/10 );
$ Result = array (
'Steps' => $ steps,
'Numbers '=> strlen ($ numbers)> 1? Substr ($ numbers, 0,-1): null,
'Dates' => strlen ($ dates)> 1? Substr ($ dates, 0,-1): null,
'Max' => $ max + $ steps
);
Return $ result;
}
