I am Ph.D student in economics.
I need to use the wavelet coherence (WTC) approach to analyze the relationship between some economics variables.
Since 2 months ago I have tried to analyze my data by using the wavelet coherence approach in RStudio. But, the scale axis numbers appeared only two figures with many zeros after decimal like(4.000000, 11.31370). The plot is attached below.
Kindly, I ask your help to make it like (4, 8, 16 , 32, 64) if possible.
Thank you in advance
