大家好！我最近做了几个样品的核磁氢谱，只有纸质版的图谱和电子版数据，我现在已经用软件把数据导入origin或excel中，但做出的图是上下锯齿状的，跟纸质版的图根本不一样。我不知道是哪里出了问题。（我选用第一列为x轴，第二列为y轴作图）
请教各位高人，我是学生物的，对核磁一窍不通，请各位不吝详细赐教。谢谢！
部分数据如下：
Number of points (Complex) = 8192
Spectral Width (Hz) = 5995.20361
Spectrometer Frequency (MHz) = 300.13181
Lowest Frequency (Hz) = -1087.76965
Digital Filter (points) = 70.184
