How to create this Graph Mapper?

Hi,

I am currently trying to replicate a grasshopper script that I had seen posted on Instagram. I was wondering if anyone can help me in figuring out how to create the graph seen in the image above. Whenever I try to make the graph it turns out curved instead of angular like seen in the image. Additionally the next command wants a point output from the graph.

Any help would be greatly appreciated.

Hi -
That’s the MD Slider.
