Charts placeholder text is too large on narrow screens
The placeholder text is set once, no matter if this a mobile or not (nor landscape/portrait, etc.). We should either use a shorter text like "No data" but less explanatory, either break the text in two (or more) lines if the text's width is bigger than the available width.
Checking the text's width is easy, breaking the text in lines is not… Should we replace any whitespace in "No data for the specific period" by a non-breaking space but the one between "for" and "the" and then split on the first breakable space found?
