Exception was thrown when using genReport to run a design file

- Bugzilla Bug (s) Resolved:

- Description:
Currently, if chart size is equal or less than zero, ChartException will be thrown for notification. This doesn't always mean error, so the exception only exists in log file.
Fixed by setting size is 1 point to avoid throwing exception from BufferedImage when size is zero, i.e. Display is NONE.
