How to get series of point for Spiral shape move its z axis along with graph mapper


I am trying to make an model according to the reference image shared, I am able to create a spiral with the series and scale component. But i am unable to move specific range of points (or i would say more room to play with height at specific controlled intervals in z- axis). To achieve the model as shown in image.

I am new to grasshopper, exploring & need help.
