[Grammar] A selection of ...are/is...

[LaMelange]

Hello teachers,
Is the following sentence grammatically correct?

A selection of these are shown in Figure 6.

I am not sure.
Thank you.

I would use "a selection of these is, etc."

https://books.google.com/ngrams/gra...;,a selection are;,c0;.t1;,a selection is;,c0

This link took me to some kind of a graph. Was this intended?

Yes, it shows you the frequencies of "a selection is" and "a selection are" in English texts.

And it shows you that both are used, but one dominates.
