'How to smooth wavelet output from python scaleogram?

I'm using the python package scaleogram to plot wavelets of a dataset in which I have one data point per day over the course of a year. The package is described here: https://www.kaggle.com/asauve/a-gentle-introduction-to-wavelet-for-data-analysis The output is all correct, but it looks very chunky at small scales. Is it possible to smooth it out at all so it looks nicer and is more readable? Here is an image of my output: enter image description here
