Here is a list of the functions defined in FusionCharts PHP Class (FusionCharts_Gen.php). These functions create the required XML output based on the parameters passed through and make the chart rendering process easier for you.

FusionCharts PHP class functions can be divided under various heads, as shown in the list below:

Instantiates chart object. Use the constructor to specify chart type, chart width, and chart height. One can also specify an ID to the chart for JavaScript Interaction. If you use the isTransparent parameter, the chart will be ready for transparent mode. To set the chart to transparent, you need to set the bgApha chart parameter using the setChartParam() or setChartParams() function.

Parameters:

• $chartType = type of the chart. To get the list of supported chart types, please click here.
• $width = numeric value for chart width in pixels.
• $height = numeric value for chart height in pixels.
• $chartID = (Optional) unique ID for the chart. Required, to use chart's JavaScript APIs.
  

  To provide cross-browser compatibility, we recommend you not to start the ID with a numerical value, nor use space as part of the ID.

  NOTE: If no ID is specified by the developer, PHP automatically generates an ID using Session and assigns it to the chart. This ID is generated using a counter variable kept in session. Hence, one every page refresh new ID will be assigned to chart. You should provide and ID to interact with the chart later using JavaScript APIs like setDataXML(), setDataURL(), print(), saveAsImage() etc.

• $isTransparent = (Optional)(true/false) prepares the chart for transparent background if set to true. To set the chart transparent, you needs to set the bgApha chart parameter using the setChartParam() or setChartParams() function.

Example:

$FC= new FusionCharts("Column3D, "350", "250");

Sets the Rendering mode of the chart. A chart can render in either Flash or JavaScript mode.

Parameters:

• $renderer = Name of the rendering mode. Possible values are javascript or flash. By default, the flash mode is set. However, in cases, where Flash Player is not found, the Renderer switches to javascript mode.

Example:

$FC= new FusionCharts("Column3D, "350", "250");
$FC->setRenderer('javascript');

Enables Print Manager for Mozilla browsers. This function adds a small JavaScript snippet to the page which enables the Managed Print option for Mozilla based browsers.

Parameters:

• $directWriteToPage = An optional parameter which when set to true will write the code directly to page. Otherwise the code snippet is returned as string.

Returns a blank string when the code is directly written to page, otherwise, the JavaScript enabling the Print Manager is returned as string.

Example:

$FC= new FusionCharts("Column3D, "350", "250");
$FC->enablePrintManager();

NOTE : The JavaScript which is generated from this code is as follows:

<script type=\"text/javascript\"><!--
  if(FusionCharts && FusionCharts.printManager) 
     FusionCharts.printManager.enabled(true);
    // -->
</script>

Explicitly sets window mode of a chart when rendered in flash mode. The possible window modes are - window, transparent and opaque. This setting will work only when chart is rendered in using flash renderer.

Parameters:

• $mode = Name of the window mode. Possible values are window, transparent and opaque.. By default, opaque mode is set to a chart.

Example:

$FC= new FusionCharts("Column3D, "350", "250");
$FC->setWindowMode('transparent');

NOTE:

Transparent mode can also be set using the constructor. This mode prepares the chart for transparent background. To set the chart transparent, you need to set the bgApha chart parameter using the setChartParam() or setChartParams() function.

Sets the delimiter for lists of chart attributes that are passed to functions like setChartParams, addDataset, addChartData, etc. Delimiter is the character used to separate consecutive attributes for various chart elements. The default delimiter is semicolon (;).

Parameter:

• $strDelm = delimiter character. The character becomes reserved and cannot be used as normal character in chart attribute values.

Note: You can use this function any number of times in a single code block for a chart. By defining a new delimiter you can use the earlier delimiter as a regular character in chart attributes.

Example :

$FC->setParamDelimiter("|");
$FC->setChartParams("caption=Monthly Report|subCaption=June;July;September|bgColor=efefdd");
$FC->setParamDelimiter("\n");
$FC->addDataset("June", "color=009900\nshowValues=0);

Sets the path of the chart SWF file. Users may need to specify the relative file path of the SWF files while using them in different applications. This function allows users to set the path. The default path for SWF file is set to the application folder itself.

Parameter:

• $SWFPath = relative path of FusionCharts SWF file(s).

Example :

$FC->setSWFPath("FusionCharts/");

Sets various chart messages. For more on chart messages please see the Changing chart messages page.

Parameter:

• $msgParam = chart messages attributes separated by delimiters. Messages attributes specified in the Changing chart messages secion are used here. Note that the attribute values must not be enclosed in single or double quotes.

Example :

$FC->setChartMessage("ChartNoDataText=Chart Data not provided;PBarLoadingText=Please Wait.The chart is loading...");

Parameters:

• $tname = name of the initializing parameters. Please refer to the table below for the list of parameter names.
• $tvalue = sets values for the initializing parameters. It can take any one of the several parameters listed below: Please refer to the table below for the possible values for each parameter name.
  
  

  Parameter Name	Range/Value	Description
  debugMode	true/false	If set to true, a debug window is displayed over the chart.
  registerWithJS	true/false	If set to true, the chart will be registered with JavaScript. This will allow JavaScript to call chart's JavaScript API.
  bgcolor	Hex Coded Color	Background color of the chart. If background color of the chart is not defined in XML, this property will be used to set the chart’s background. For example, #ff0000
  scaleMode	noscale or exactfit or noborder or showall	Scaling option of the chart. It can take any value out of the four: "noscale", "exactfit", "noborder" and "showall".

$FC->setDataBaseType("oracle");

or

$FC->setDataBaseType("mysql");

Creates the set of chart Category Names from database for database driven multi-series charts.

Parameters:

• $query_result = the SQL query result as resource.
• $categoryColumn = database field name for category names.

Example:

$strQuery = "select distinct weekNames from Sales";
$result = mysql_query($strQuery);

$FC->addCategoryFromDatabase($result, "weekNames");

For detailed examples on FusionCharts PHP Class' Database Handling functions please go through the Using with PHP Class section.

Adds datasets with data values for each dataset (only for multiseries/stacked/combination charts) from database.

Parameters:

• $query_result = SQL query result to fetch dataset from database.
• $ctrlField = Control Break field. The database field that contains all series names in sorted order; the function uses this parameter to pick series names for multiple datasets.
• $valueField = the field that contains the dataset values.
• $datasetParamArray = (Optional) an array that stores delimiter separated list of attributes for each dataset.
• $link = (Optional) Adds hyperlink feature to dataplots. This adds the link attribute to dataplots or <set> elements.It can be a simple URL say, "http://www.google.com" or another page say, "Drill/Detailed.php" etc. For details on drill down and creating links using FusionCharts XT, please go through the section Drill Down Charts.
  
  This parameter has a link place holder format that helps creating dynamic links. Anything placed between ## and ##
  (for example, . FactoryID in "Detailed.php?FId=##FactoryID##") will be regarded as a field/column name in the SQL query result. Value from that column will dynamically replace that place holder. Hence, for each dataplot in the chart the link values will be different.
  
  For detailed example on this feature, please refer to Creating Drilldown charts in "Using With PHP Class" section.
  

Note: The control Break field must be sorted.

Example:

$strQuery = "select  weekNames,revenue from Sales order by weekNames";
$result = mysql_query($strQuery);

$FC->addDatasetsFromDatabase($result, "weekNames", "revenue");

This function is used to get the full XML required for chart generation. FusionCharts PHP Class functions build specific parts of chart XML. getXML() function assembles those parts and returns the full XML. Users can use this XML to render charts in Data URL method.

Return Type:

• Chart XML as string.

Example:

$xml=$FC->getXML();

This function builds the full XML required for chart generation and also renders chart based on chart type, width and height as specified. This function does not accept any parameter, nor does it return any value.

Parameter:

• $renderAsHTML = (true/false) renders the chart using HTML embedding method if set true. Note that this method does not make use of FusionCharts.js. This HTML embedding method is helpful where JavaScript is disabled or in AJAX Portback.
  
  
• $display = (true/false) ask the render() function to directly display the chart or to return the rendered HTML of the chart to a variable. The default value is true. If sets to false, the function will return the rendered HTML as string. Otherwise, the chart is normally printed to the response buffer.

Return Type: mixed

• If $display is set to false it returns the rendered HTML of the chart as string.
• If $display is set to true it returns true.

Example:

$chartHTML = $FC->renderChart(true, false);

This function is deprecated. Please use renderChartFromExtData() instead.

Renders chart from XML which has not been created in the program. After creating chart object and setting relative SWF file path, this function can be used where the full XML is passed through.

Parameter:

• $dataXML = full XML for chart rendering in string format
• $renderAsHTML = (Optional)(true/false) renders the chart using HTML embedding method if set true.

Example:

$xml="<chart><set value='100' name='Product A'/><set value='120' name='Product B'/></chart>";
$FC = new FusionCharts("Column3D","300","250");
$FC->renderChartFromExtXML($xml);

Renders chart from data which has not been created through the class. After creating chart object and setting relative chart file path, this function can be called to set complete XML or JSON to the chart. 

The XML or JSON data needs to be passed as string. You can convert an array to proper JSON string using PHP's json_encode function.

To know more on XML, please read the FusionCharts XT Data Formats > XML section.

To know more on JSON, please read the FusionCharts XT Data Formats > JSON section.

Parameter:

• $data = full XML/JSON data for chart rendering. The data should be provided in string format
• $dataformat = (optional) defines the data type of the data passed through this function. The possible values are xml and json. The default value is xml.
• $renderAsHTML = (Optional)(true/false) renders the chart using HTML embedding method if set true. This setting is not applicable if json data is used.

Example:

$data = array(
	"chart"=> array( 
		"caption" => "Weekly Sales Summary" ,
		"xAxisName" => "Week",
		"yAxisName" => "Sales",
		"numberPrefix" => "$"
	),
	"data" => array(                   
		array( "label" => "Week 1", "value" => "14400" ),
		array( "label" => "Week 2", "value" => "19600" ),
		array( "label" => "Week 3", "value" => "24000" ),
		array( "label" => "Week 4", "value" => "15700" )
 	)
);
	
	
	$json= json_encode($data);;
	$FC = new FusionCharts("Column3D","300","250");
	$FC->renderChartFromExtData($json, 'json' );
