Summary
| Description |
English: Bifurcation diagram of complex quadratic map.
Horizontal axis ( real slice of Mandelbrot set ) is divided int 3 segments with nonlinear scale:
Colors:
Each window has non-linear, i.e. logarithmic x-axis scale: case TypSkalOsiXY of
liniowe : begin
okno.Ax:=(okno.Dxe)/(okno.dx); { XE=Ax*x+Bx }
okno.Bx:=XEmin-(okno.Ax*Xmin);

okno.Ay:=(okno.Dye)/(okno.dy);
okno.By:=YEmin-(okno.Ay*Ymin);
okno.KrokY:=(okno.Dy)/(okno.dye);
end;
