Welcome to the board.
I think if I were to show the key components between EBITDA and Net Profit I would probably go for a waterfall chart. Are you just looking at a single period (month/qtr/year)?
See waterfall chart tutorial here.
The "initial" would be EBITDA and the "final" net profit. Not knowing your P&L I would only be able to speculate what items fall below the line, but I presume you have a bunch of GL account codes that apply; and perhaps that you can further categorise.
