PSD scale issue

Hi,

I have calculated PSD, but scales for topoplot and power plot look different!? In case of topoplot it is 10-13.

I converted it to relative power through standardization procedure, again scales are different between topoplot and power plot (10-13 vs 10+4):

You can change the configuration of each figure separately.
Click on figure, then adjust the way you want to display the values in the Display tab.

To configure the colormap, get back to the corresponding tutorial:
