Thanks - that works.
May I suggest to change the documentation from:
--8<---------------cut here---------------start------------->8---
text.width: the width of the legend text in x (‘"user"’) coordinates.
(Should be positive even for a reversed x axis.) Defaults to
the proper value computed by ‘strwidth(legend)’.
--8<---------------cut here---------------end--------------->8---
to
--8<---------------cut here---------------start------------->8---
text.width: the width of the legend text in x (‘"user"’) coordinates.
(Should be positive even for a reversed x axis.) If set,
it is used to compute the width of the legend box. Defaults to
the proper value computed by ‘strwidth(legend)’.
--8<---------------cut here---------------end--------------->8---
to make this clear?

True - but no other parameter to achieve this? Equivalent to text.widht?
Thanks
