CutoffScale¶
- class CutoffScale(*args)[source]¶
Bases:
proplot.scale._Scale
,matplotlib.scale.ScaleBase
Axis scale composed of arbitrary piecewise linear transformations. The axis can undergo discrete jumps, “accelerations”, or “decelerations” between successive thresholds.
- Parameters
*args (
thresh_1
,scale_1
,...
,thresh_N
,[scale_N]
, optional) – Sequence of “thresholds” and “scales”. If the final scale is omitted (i.e. you passed an odd number of arguments) it is set to1
. Eachscale_i
in the sequence can be interpreted as follows:If
scale_i < 1
, the axis is decelerated fromthresh_i
tothresh_i+1
. Forscale_N
, the axis is decelerated everywhere abovethresh_N
.If
scale_i > 1
, the axis is accelerated fromthresh_i
tothresh_i+1
. Forscale_N
, the axis is accelerated everywhere abovethresh_N
.If
scale_i == numpy.inf
, the axis discretely jumps fromthresh_i
tothresh_i+1
. The final scalescale_N
cannot benumpy.inf
.
Example
>>> import proplot as pplt >>> import numpy as np >>> scale = pplt.CutoffScale(10, 0.5) # move slower above 10 >>> scale = pplt.CutoffScale(10, 2, 20) # move faster between 10 and 20 >>> scale = pplt.CutoffScale(10, np.inf, 20) # jump from 10 to 20
