Dot's wrong to indicate (5,3)
I believe the answer is:
point out
'indicate' is the definition.
(pointing out is a kind of indicating)
'dot's wrong' is the wordplay.
'dot' becomes 'point' ('point' can be a synonym of 'dot').
'wrong' becomes 'out' (eg a calculation might be 'out').
'point'+'out'='POINT OUT'
'to' acts as a link.
(Other definitions for point out that I've seen before include "Bring up" , "Specify" , "Make clear" , "Indicate, draw attention to" .)
