我有两个数据向量$y1$和$y2$，我想将它们都绘制为向量的函数$x$. 我希望结果是两条重叠的曲线。这是我正在使用的一组命令。

y2=[0.003,0.003,0.011,0.011,0.015,0.020,0.023,0.024,0.024,0.024,0.024,0.024,0.024,0.025,0.024,0.024,0.024,0.024,0.0224,0.0214,0.0.0. ,0.019,0.018,0.016,0.013,0.011,0.009,0.009,0.009]; y1=[0.003,0.003,0.003,0.010,0.031,0.050,0.060,0.065,0.070,0.074,0.079,0.085,0.087,0.087,0.091,0.090,0.090,0.086,0.0580,0.027,0.0.0. ,0.044,0.035,0.032,0.026,0.018,0.013,0.013,0.013,0.003]; x=[20,70,100,150,200,220,240,250,260,270,280,290,300,310,320,330,340,350,360,370,380,400,450,500,550,600,700,800,1000,1500,000,200,200,000,000,000,000,700,800,1000,1500,000, 情节（x，y1，y2）。

哪个确实绘制了向量，除了$y2$从 0 映射到 20，而$y1$从 20 映射到 3000。这是上述命令的结果。

$y2$是橙色图。我真的无法比这更好地描述这个问题。我应该如何重写我的命令，以便$y2$也是从20映射到3000？
