CartesianAxes.dualy(arg, **kwargs)[source]

Return a secondary y axis for denoting equivalent y coordinates in alternate units.

  • arg (function, (function, function), or scale-spec) – Used to transform units from the parent axis to the secondary axis. This can be a FuncScale itself or a function, (function, function) tuple, or an axis scale specification interpreted by the Scale constructor function, any of which will be used to build a FuncScale and applied to the dual axis (see FuncScale for details).

  • lim, reverse, scale, label, tickdir, grid, gridminor, tickminor, ticklabeldir, tickrange, wraprange, rotation, formatter, ticklabels, ticks, locator, minorticks, minorlocator, bounds, margin, color, ticklen, linewidth, gridcolor, label_kw, scale_kw, locator_kw, formatter_kw, minorlocator_kw (optional) – Prepended with 'y' and passed to Axes.format.
