Generating A Series With Uneven Step Size

Hi Grasshopper Community,

Im a new and inexperienced grasshopper user. I am trying to generate a series of numbers, between the domain 0 - 180, for input into the Rotate Component's 'Angle Input'. What i am trying to achieve is a dynamic list, which can be easily altered, and where the values start at 0 and end at 180, but where the step size starts off small and gets progressively larger, as if it were influenced by a parabolic expression. I have put this together (see image) by playing around and it does the trick, but I assume there is probably a better and more dynamic way to achieve this? I have very little experience and understanding of the graph mapper component, and especially what should be input into it, and how the X and Y domains for the graph should be set up and exactly what it is that they influence. Any help or advice would be greatly appreciated. I have included the grasshopper definition file also, should it help.

THANKS!

Here's one way. You generate a list if numbers between zero and one. You run them through a Graph Mapper which also has domains zero to one. This way you know the visible part of the graph is acting on all your values, ie. nothing is going on out of view. You take your graphed numbers and map them from the 0~1 domain to the 0~180 domain.

Thanks David for your prompt and simple solution! Your help is greatly appreciated. Out of curiosity, is there any learning material you would recommend in order to gain a better understanding of the graph mapper component?
