matplotlib.axes.Axes.loglog

Axes.loglog(self, \*args, \*\*kwargs)

Make a plot with log scaling on both the x and y axis.

Call signatures:

loglog([x], y, [fmt], data=None, **kwargs)
loglog([x], y, [fmt], [x2], y2, [fmt2], ..., **kwargs)

This is just a thin wrapper around plot which additionally changes both the x-axis and the y-axis to log scaling. All of the concepts and parameters of plot can be used here as well.

The additional parameters basex/y, subsx/y and nonposx/y control the x/y-axis properties. They are just forwarded to Axes.set_xscale and Axes.set_yscale.

Parameters:

basex, baseyscalar, optional, default 10

Base of the x/y logarithm.

subsx, subsysequence, optional

The location of the minor x/y ticks. If None, reasonable locations are automatically chosen depending on the number of decades in the plot. See Axes.set_xscale / Axes.set_yscale for details.

nonposx, nonposy{'mask', 'clip'}, optional, default 'mask'

Non-positive values in x or y can be masked as invalid, or clipped to a very small positive number.

Returns:

lines

A list of Line2D objects representing the plotted data.

Other Parameters:

**kwargs

All parameters supported by plot.
