Dynamic Legend with auto line break

Hey guys,

I am using a DynamicLegend.

with the following code:

legend(ax(2),'-DynamicLegend', 'Orientation','horizontal','FontSize',5, 'location', 'southoutside'); 

But if the text is too long.... it only cuts it and dont do a linebreak.

With this code it is ok but i dont want it vertical

legend(ax(1),'-DynamicLegend','FontSize',5, 'location', 'southoutside'); 

Is there a option to do a "auto linebreak" ?

thanks in advance.
