Can you tell me a solution?

I want to know how to express this equations to graph.

x-axial = x, y-axial = I

I used equations nodes, for loop, shift register.

But I felt difficult because of two variances.

I think this is what you mean.

It would be better if you post these types of questions to the regular labview forums in the future (this is the user interface group).
