各位同仁、各位朋友，大家好！
我需要绘制以下曲线。你能帮我一下吗？
前几天我尽力了，但是情节内外的标签却遇到了严重的问题。
以下是训练和测试的坐标：
火车：[1.1257,0.9836,0.9558,0.9431,0.9359,0.931,0.9277,0.9252,0.9233,0.9219,0.9205,0.9197,0.9189,0.9182,0.9177,0.9172,0.9168,0.9165,0.9162,0.9159,0.9157,0.9155,0.9153,0.9152,0.915,0.9149,0.9147,0.9146,0.9145,0.9143,0.9143， 0.9142,0.9141,0.914,0.914,0.914,0.9139,0.9138,0.9137,0.9137,0.9136,0.9136,0.9136,0.9136,0.9135,0.9134,0.9134,0.9134,0.9133,0.9132]
测试：[1.1257,0.992,0.9681,0.9579,0.9521,0.9485,0.9457,0.9445,0.9432,0.9424,0.9413,0.9409,0.9409,0.9408,0.9402,0.9397,0.94,0.9397,0.9397,0.9392,0.9397,0.9395,0.9393,0.9398,0.9389,0.9394,0.9393,0.9396,0.9394,0.9393,0.9392， 0.939,0.9389,0.9394,0.9393,0.9385,0.939,0.9393,0.9392,0.9395,0.9392,0.9396,0.9394,0.9391,0.9397,0.9393,0.9391,0.9397,0.9392,0.9393]
