Hi,
The only way to length chart textboxes is with more text. But at some
point more text will cause the content to wrap. The charts textboxes do
not have the ability to be sized manually even though the bounding box
and grab handles would suggest otherwise.
Try adding a few spaces or even non-breaking spaces ALT+0160 (Numpad)
Cheers
Andy
