ytransform Specify a transformation to be applied to all y-data

Call signature:

ytransform(foo=None)

Help text:

ytransform(foo), where foo is a callable that accepts numpy arrays, specifies a transformation to apply to all y-data.
ytransform(None) reverts to linear plotting.

See xtransform for more details.

Example:

import qplot as qp

import numpy as np

qp.figure('ytransform', 3, 3)

yy = np.exp(np.random.randn(100))

xx = np.random.randn(100)

qp.ytransform(lambda x: np.log10(x))

qp.marker('o', 2)

qp.mark(xx, yy)

qp.yaxis(ticks=[.1, 1, 10], x=-3)

qp.minorticks(np.arange(.2,1,.1))

qp.minorticks(np.arange(2,10,1))

qp.xaxis(ticks=qp.arange(-2,2,1), y=np.exp(-3))
