[Funnel Chart Error in jcharfx.system.js]

Hi, 

I have using funnel chart in my application. I am getting the data to the chart from ajax call and setting data to chart.

If no data is present, I am getting the below error.

 Error: Invalid value for attribute cy="NaN"    in jcharfx.system.js

Please anyone help me in resolving this issue.

Thanks,

Naresh.
