x axis

The determination curves are displayed from the

for cathodic sweeps: from + to -). For cyclic
sweeps, the forward sweep is displayed from the
left to the right.

y axis

The y axis is always displayed from the bottom to
the top with the same direction as the x axis (for
anodic sweeps: from - to +; for cathodic sweeps:
from + to -).
