Matching table row height with Subplot height

I am trying to build chart like this .

I was able to complete chart(Bar chart with base property) & table seperatly . but the challenge I am facing is,while integrating, I have to stretch the height of each row in table to match with height of subplot. as marked in screen shot dynamically.
no of subplots are not same always , it will change based on user selection. is there a way to get rendered subplot height in pixels ,so that we assign it to table row.

any thoughts & suggestions on this.
