Specifies the encoding of strings used in methods arguments.

void object->SetEncoding( int encoding )

Arguments

object: Required. A Chart object.
encoding: Required. An integer value which specifies the type of encoding.

Remarks

The default encoding is the standard PHP encoding. However it is sometimes usefull to directly specify UTF-8 strings in methods arguments instead of using the standard encoding.

The possible encodings are:

Value	Constant	Definition
0	SWIFFCHART_DEFAULT_ENCODING	Use the default PHP encoding
1	SWIFFCHART_UTF8_ENCODING	Directly use UTF-8 strings

PHP Sample Code

The following PHP code illustrates use of the SetEncoding method.

// $title and $subtitle are UTF-8 encoded strings
$title= "Wikipedia: L'encyclop\xC3\xA9die libre";
$subtitle= utf8_encode( html_entity_decode("Wikipedia: Die freie Enzyklop&auml;die") );

// Set UTF-8 encoding
$chart->SetEncoding( SWIFFCHART_UTF8_ENCODING );

// the UTF-8 strings can now be directly used by the API
$chart->SetTitle($title);
$chart->SetSubtitle($subtitle);

// print them in the html page
print htmlentities( utf8_decode($chart->GetTitle()) )."<br>";
print htmlentities( utf8_decode($chart->GetSubtitle()) )."<br>";
