When using dataURL method
If you're using dataURL method, you can directly embed the Franc character in your XML and then use it as under:
 
<chart caption='Sales distribution by Employee' subCaption='Jan 07 - Jul 07' numberPrefix='₣' isSliced='1'>
   <set label='Buchanan' value='20000' />
   <set label='Callahan' value='49000' />
   <set label='Davolio' value='63000' />
   <set label='Dodsworth' value='41000' />
   <set label='Fuller' value='74000' />
</chart>
 
You'll now get the following output:
 
 
When using dataXML method
When using dataXML method, you need to encode Franc character to %E2%82%A3 - else, you'll get an error on many browsers. Following is the full HTML Code to embed the chart:
 

<div id="chart1div">
   This text is replaced by the chart.
</div>
<script type="text/javascript">
   var chart1 = new FusionCharts("Pyramid.swf", "ChId1", "400", "350", "0", "0");
   chart1.setDataXML("<chart caption='Sales distribution by Employee' subCaption='Jan 07 - Jul 07' numberPrefix='%E2%82%A3' isSliced='1'><set label='Buchanan' value='20000' /><set label='Callahan' value='49000' /><set label='Davolio' value='63000' /><set label='Dodsworth' value='41000' /><set label='Fuller' value='74000' /></chart>");
   chart1.render("chart1div");
</script>

 
You will get the same output as earlier.
