First of all, thank you all for sharing this material. It's being extremely useful for me!
I have slightly modified this code to adapt it to my case of study and I'm wondering if, with regards to CWT, I could visualize period instead of frequencies in the output image. Although it's being a little hard for me to enter into waveletes world, I think I'd have to make a deeper change beyond invertis y-axis, isn't it?
I'd really appreciate someone's aid. Thank you very much in advance.
Kind regards,
Miguel González-Jiménez

Hi Steve!
Thank you for your response and that web-link, it's been helpful. I have already tunned your code: what I did finally was obtained the periods just by inverting the frequencies array, and then I plotted them on a log2 scale image for a better visualization.
What I'm hesitating right now is if, somehow, I could plot the arrows in the output XWT image using some of the functions you have programmed, like xwt_phase, so as to obtain a graphic like the one attached.
Thank you again! I hope you're fine.
