Adjust exponent increment, x, y stretch, offsets & color. These are exponential relationships. Looks like a tulip bulb to me.
Revised from my earlier version to have continuous exponent functions, and less code. Ranging x and y from 0 to 1 makes it easier to graph in a concise and beautiful way. One pen line for each exponent from 0 to 20 and a large range of fractional exponents. Labelled a few functions. Those labels only appear for whole number exponents and whole number fractional exponents. Set exponent increment to 10 to see labels most clearly.
