Disliked{quote} Hi Jerry, I hope you are well. I was wondering, what parameters need to be used for Spectrum analysis of 4 hourly graph? I was trying to do it, but the Harmonic Box is generating the curve for 2023 and after, 2-3 years from the last bar. Tried different setup, but I do not know what is wrong. Have you had an experience of working with 4H graph?Ignored
