Hi All,
Ive seen the following article on how to create parameters and allow user input to crete what if analyses.
http://www.evolytics.com/blog/tableau-201-how-to-make-a-what-if-analysis-using-parameters/
The output appears linear. I.e If investment is increased by 5%, sales increase 5%.
I was hoping the expand on this with the following. How would I create the functionality to refer to an investment v revenue table. i.e a non linear curve so for example if investment (Y) is increased by 5%, the revenue increases by X%. The x and y would be defined in a reference table. The attached image is graphical representation of this table.
Thanks
