Matplotlib 2.x By Example

Advanced example

Alternatively, pyplot.loglog() can be used to make a plot with log scaling on both the x and y axes instead of specifying the scale after running pyplot.plot(). In the following complete example, we are going to combine the use of tick formatters to display the y axis in natural log scale, as well as the use of keyword argument basex to display the x axis in log₂ scale:

import numpy as npimport matplotlib.pyplot as pltfrom matplotlib.ticker import FuncFormatterdef ticks(y, pos):    """ Method that formats the axis labels to natural log scale     """        # Use Python string formatter to limit the number of decimal places    # for float values.     # The precision of the formatted float value can be specified using  # a full stop, followed ...
