宿舍更换的新淋浴喷头"水温vs旋钮角度"关系的研究(曲线)

应该非常一目了然了吧. 

假设是Mathematica,能够用这种代码模拟曲线部分:

With[{yslice1 = .5, yslice2 = -.8},
 GraphicsGrid[{{Plot[{ArcTan[-x], 1.5, -1.2}, {x, -5, 5},
     Axes -> False, Frame -> False,
     PlotStyle -> {Blue, Red, Green}]}, {Plot[{ArcTan[-x*10],
      1.35, -1.35}, {x, -5, 5}, Axes -> False, Frame -> False,
     PlotStyle -> {Blue, Red, Green}]}},
  Spacings -> {Scaled[0.1], Scaled[.5]}]]
