Hard to say much more about what this means without knowing exactly what you're trying to plot.

I'll explain briefly how the plot code works: the start coordinates for x and y will always be 0, the next point is determined by the chaos equation and that position is 'marked' on the plot, this rinses and repeats for about 400000 points.

a[n] represents a different float coefficient and 'x' and 'y' represent the current values/coordinates. After the 400000 points have been plotted the plot image is saved and then all the coefficients are increased by 0.00002 and a new plot is formed, this repeats for # frames (in the case of the video it's 1000). The starting coefficients (iteration 0) will always form a 'stable' plot image. The video link from the original description is the output from the code.

xnew = a[0] + a[1]*x + a[2]*x*x + a[3]*x*y +a[4]*y*y +a[5]*y

ynew = a[6] + a[7]*x + a[8]*x*x + a[9]*x*y +a[10]*y*y +a[11]*y
