我试图计算/可视化两个时间序列之间的时间滞后（我想知道房间内外湿度变化之间的时间滞后）。
我的系列中的每个数据点都是每小时采集一次的。将这两个系列放在一起，我可以清楚地看到它们之间的变化：Sorry for hiding the axis
下面是我的时间序列数据的一部分。我将把它们打包成2个数组：

我知道互相关是一个正确的术语，但过了一段时间，我还是不知道要使用scipy.signal.correlate和numpy.correlate，因为我得到的只是一个充满NaN的数组，所以显然我需要更多这方面的知识。
我希望得到的结果可能是一个类似于How to make a correlation plot with a certain lag of two time series线程的答案部分的图，在这里我可以看到最有可能的时滞是多少小时。
