Report Chart Disapears

Report Chart Disapears

Hello,
Typically when I choose a report the upper right exhibits 4 functions as follows:
"EXPORT" "SEND EMAIL" "EDIT" "CHART OPTIONS"

When I edit and run a new (Summary) report these functions are replaced with the following:
"SAVE" "EDIT" "CANCEL"

The question, what happened to "CHART OPTIONS"?
Also, the chart itself disapears.

Please help so I can see charts once I run a new summary report.

Thanks,
