Graphs and Charts output in XML Publisher Report

Hi All,
I have incorporated the graphs and charts as well as some bitmap images in XML Report (RTF File), When i am taking a output in pdf. it is coming fine and working properly, where as while taking the same output in excel, graphs/charts/bitmap images are not getting displayed. Only you can view the data.
can you please suggest what's the issue on the same and how can be resolved.
Thanks & Regards
Ankur Dawra
