How to plot power of wavelet transform.

Dear You!

I have a data set in time series (time is days) and I want to use wavelet transform to analysis it. I have not knew how to plot it's power as figure which I attached (the curve is on the right side). I would like to receiver help from you. Thanks so much.

Best regards
