I need help regarding the display of a dynamic value

Currently I'm working on a pretty simple project, which is meant to be a first step towards derivatives. You should be able to see it yourself using the data I uploaded. As you can see I defined "a" to be the quotient of "j" and "i" and I want to display the value of "a" in my graphic too and not only on the left side only. How do i do this? I tried to implement a textbox and typed in "\frac{j}{i}", but it just shows me a fraction with variables in it, it seems to be unable to grab the values for "j" and "i", compute it and show the result in the textbox.
