Hi there,
I'm doing a program that shows both points and text in a colored-spiral:
Now I'm trying to get letters/text to alternate with the points in the spiral. Problem is how do I set this up? How do I get text to go into the spiral along with the points?
Here is the code, just copy and paste, then run to see how it works. Certain code I commented out in regards to using "String" and "text" and it wasn't really working.
Any suggestions are great. PLEASE!!!
