Hi,
Below is the XML that I am using:
<chart caption='Pie Chart 1' pieradius='70' showZeroPies='1' enableSmartLabels='1' isSmartLineSlanted='1' labelSepChar='t' skipOverlapLabels='0' showLabels='1' showPercentValues='1' showValues='1'>
<set label='Test1' value='30' />
<set label='Test2' value='40' />
<set label='Test3' value='10' />
</chart>
Thanks,
Tanuja
