Generating a table of values and a plot

[vic]

The task I have is: given a input cell, and an output cell (depending on the input cell via biiig block of data and intermediate computations) , create a plot of the output vs input.
So, I can create a long list of input values.
Then what is the easiest way to make planmaker use each input value into the input cell, and compute a corresponding list of ouput values from the Output cell?
So that I can then plot them.

Thank you
