Does it make a dent in the good weather chart? (10)
I believe the answer is:
depression
'dent in the good weather chart?' is the definition.
'depression' can be an answer for 'dent' (synonyms). I am not sure about the 'in the good weather chart?' bit.
'does it make a' is the wordplay.
I cannot really understand how this works, but
'it' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' is present in the answer.
'make' could be 'press' (pressing is a kind of making) and 'press' is located in the answer.
The remaining letters 'dion' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for depression that I've seen before include "Nineteen twenty nine financial slump" , "Bad times" , "mental anguish" , "despair" , "valley" .)
