Hey all,
Here is how you generate flash charts based on a XML data source using PHP.The data is retrieved from DB and written to a xml file. I created a CCS page called 'ExampleChart'.
$db = new clsDB<ConnectionName>();
$strQuery ="select field1, field2 from tablename ...... " ;
$db->query($strQuery);
$rows=$db->num_rows($db->f("field1")); //get number of rows returned by the query
$Array1=array();
$Array2=array();
$i=0;
while($db->next_record())
{
$Array1[$i] = $db->f("field1");
$Array2$i]=$db->f("field2");
$i++;
}
$strXML ="<chart><chart_data><row><null/>";// xml generation
for($i=0;$i<$rows;$i++)
$strXML.="<string>".$field1[$i]."</string>";
$strXML.="</row><row><string></string>";
for($i=0;$i<$rows;$i++)
$strXML.="<number>".$field2[$i]."</number>";
$strXML.="</row></chart_data><chart_grid_h alpha='20' color='000000' thickness='0' type='solid' />";
$strXML.="<chart_rect positive_color='ffffff' positive_alpha='20' negative_color='ff0000' negative_alpha='10' />";
$strXML.="<chart_type>pie</chart_type>";
$strXML.="<chart_value color='ffffff' alpha='90' font='arial' bold='true' size='10' position='inside' prefix='' suffix='' decimals='0' separator='' as_percentage='false' />";
$strXML.="<draw>";
$strXML.="<text color='000000' alpha='10' font='arial' rotation='0' bold='true' size='30' x='0' y='140' width='400' height='150' h_align='center' v_align='bottom'>|||||||||||||||||||||||||||||||||||||||||||||||</text></draw>";
$strXML.="<legend_label layout='horizontal' bullet='circle' font='arial' bold='true' size='9' color='ffffff' alpha='85'/>";
$strXML.="<legend_rect fill_color='ffffff' fill_alpha='10' line_color='000000' line_alpha='0' line_thickness='0' /></chart>";
$strXML.="<series_color><color>ddaa41</color><color>88dd11</color><color>4e62dd</color><color>ff8811</color><color>4d4d4d</color><color>5a4b6e</color></series_color></chart>";
// The xml string has been constructed.. We now dump this string into a XML file
$myfile="Dir/example.xml";
$myfilehandle= fopen($myfile, 'w') or die("can't open file");
fclose($myfilehandle);
$fh = fopen($myfile, 'w') or die("can't open file");
fwrite($fh, $strXML);
fclose($fh);
$db->close();
This code is written in my page's(ExampleChart) Before Show event
To actually render the chart I created a html page called example.html. I provided a Link on ExampleChart to 'example.html'
This is the html source of 'example.html':
<body>
<OBJECT classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"
