I will try to describe the iterations of chart development as my knowledge and the code complexity evolves. Going through tutorials is a crawl-walk-run, building-block process. Effective, but frustrating to document whilst implementing multiple and sometimes redundant techniques.
A simple table of values, with polar coordinates (r, θ) in the first two columns, and their corresponding Cartesian coordinates (x, y) in columns three and four. The chart is an image of the Cartesian plot in MS Excel.
Length r | Angle θ | x | y |
