BIRT 2.3.2 Chart to Excel, possible?

Hello everyone,

I have report that has both tabular and chart (bar graph) in it, when I export it in pdf and doc format the chart works fine, but when I export it into excel (xls) format the chart were gone and the table was intact. Could any one help me if BIRT 2.3.2 can do it and how?

Thanks in advance!
God bless.
