一種方法是使用ContourPlot

讓我們在總結其操縱使其更容易調整

Manipulate[ 

With[{f1 = y == x - x^3, f2 = x == y^3 - y}, 
    ContourPlot[{f1, f2}, {x, -lim, lim}, {y, -lim, lim}, 
    Frame -> True, 
    FrameLabel -> {{y, None}, {x, {f1, f2}}}, 
    ImagePadding -> 30, 
    GridLines -> Automatic, 
    GridLinesStyle -> Directive[Thickness[.001], LightGray]] 
    ], 

{{lim, 3, "limit"}, .1, 10, .1, Appearance -> "Labeled"} 
] 

enter image description here
