Hi, I have a geoelectrical profile that has been surveyed by 8 VES's. I am using the ERT field with topography procedure to invert my field data. before inversion, I try to visualize my observed data by ert.showData() and my data gets illustrated like the image I upload here. I wonder if there is a way to kinda interpolate my data for visualization or something like that just to get a better depicted output. I also have some vague points about the lables on the y-axis. I would appreciate it if you give me a brief explanation about that too.
