matplotlib.axes.Axes.semilogx

Axes.semilogx(*args, **kwargs)

Make a plot with log scaling on the x axis.

Call signature:

semilogx(*args, **kwargs)

semilogx() supports all the keyword arguments of plot() and matplotlib.axes.Axes.set_xscale().

Notable keyword arguments:

basex: scalar > 1

Base of the x logarithm

subsx: [ None | sequence ]

The location of the minor xticks; None defaults to autosubs, which depend on the number of decades in the plot; see set_xscale() for details.

nonposx: [ ‘mask’ | ‘clip’ ]

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

The remaining valid kwargs are Line2D properties:
