In chemistry, what is the abscissa represented by logj ordinate with potential?

in the polarization curve, the abscissa can represent the current density, and the ordinate represents the electrode potential. According to the query related information, the curve showing the relationship between electrode potential and current density is called polarization curve. In the polarization curve, the abscissa can represent the current density and the ordinate the electrode potential. It is also possible to use the abscissa to represent the electrode potential and the ordinate to represent the current density, which depends on the research object and research method. Each point on the curve represents the electrode potential at this current density.
