render_chart(chart_swf,str_url,str_xml,chart_id,chart_width,chart_height,debug_mode,register_with_js,&block)

This function creates the javascript code that renders a chart from the swf file passed as parameter either making use of setDataURL method or setDataXML method.

parameter chart_swf : Path to the swf file (includin the filename) that renders the chart.
parameter str_url : If you intend to use dataURL method for the chart, pass the URL to the XML as this parameter. Else, set it to ""
parameter str_xml : If you intend to use dataXML method for this chart, pass the XML data as this parameter. Else, set it to ""
parameter chart_id : string for identifying chart. Unique Id for the chart, using which it will be recognized in the HTML page.
parameter chart_width : integer, Intended width for the chart (in pixels)
parameter chart_height : integer, Intended height for the chart (in pixels)
parameter debug_mode : boolean (true/false), Whether to start the chart in debug mode.
parameter register_with_js : pass value as true ( a boolean ) for view file to be registered to include javascript statements.
