The error comes from the auto-computing of the size of the label bounding box according to the current Font Context (size, etc.)
Since the ChartPanel is not open, Graphics2D object is null.
The label box has been temporarily removed from the "Export\Chart..." command process.

Before fully fixing the problem, need to see if we keep the "Export\Chart..." command.
