我想拟合一个正弦曲线，因此它不是线性回归，具有以下数据：

time = ['18','22','26','30','34','38','42','46','50','54','58','62']

expression = ['137.155037','384.090397','364.917828','129.681188','440.178499','381.781172','240.07136','178.45994','333.531072','376.431044','216.010247','234.118949']

以下是其他绘图的其他数据：

time = ['18','62']

expression = ['745.714373','628.422864','549.446547','1198.588819','860.454725','894.285159','526.084893','462.250869','765.354678','1206.71841','982.601396','855.513742']
