Nowadays, this is very rarely done - the modern system is open; punctuation is only used when necessary. There is one situation where a full stop would appear at the end of the legend and that's when the legend contains more than one sentence. For example:
This shows Mozart and Saliari. Mozart is the one in the hat. Has a full stop at the end, because it contains two sentences and it would look odd if the second sentence had no full stop.
Historically - perhaps 50 years ago; punctuation was used far more often - a newspaper headline might be:
The B.B.C. is to Broadcast Pictures by Wireless. With a full stop at the end and "BBC" written as "B.B.C.".
an open plan figure is a figure whose end point are not connected
A line
A straight line other than a line segment which does have end points.
No, it has 5. The 0 at the end is not a place holder and so is (or should be) an indicator of the precision of the number. In that case it is also a significant figure.
an angle
well let me think........ oh yes! animperative sentences always ends with a f.s( fullstop if any of you idiotsdon'tknow)
There may or may not be a full stop at the end of a sentence fragment. It is the grammatical content that determines whether it is a fragment. For example, 'She opened the' is a fragment, whether there is a full stop after it or not.
