class SymmetricalLogScale(**kwargs)[source]

Bases: proplot.axistools._ScaleBase, matplotlib.scale.SymmetricalLogScale

As with SymmetricLogScale. AutoFormatter is the new default major formatter. Also, “x” and “y” versions of each keyword argument are no longer required.

  • base (float, optional) – The base of the logarithm. Default is 10.

  • linthresh (float, optional) – Defines the range (-linthresh, linthresh), within which the plot is linear. This avoids having the plot go to infinity around zero. Defaults to 2.

  • linscale (float, optional) – This allows the linear range (-linthresh, linthresh) to be stretched relative to the logarithmic range. Its value is the number of decades to use for each half of the linear range. For example, when linscale is 1 (the default), the space used for the positive and negative halves of the linear range will be equal to one decade in the logarithmic range.

  • subs (sequence of int, optional) – Default minor tick locations are on these multiples of each power of the base. For example, subs=(1, 2, 5) draws ticks on 1, 2, 5, 10, 20, 50, 100, 200, 500, etc. The default is subs=numpy.arange(1, 10).

  • basex, basey, linthreshx, linthreshy, linscalex, linscaley, subsx, subsy – Aliases for the above keywords. These used to be conditional on the name of the axis.
