matplotlib.pyplot.semilogx

matplotlib.pyplot.semilogx(*args, **kwargs)

Make a plot with log scaling on the x axis.

Parameters:

basex : float, optional

Base of the x logarithm. The scalar should be larger than 1.

subsx : array_like, optional

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 : string, optional, {‘mask’, ‘clip’}

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

Returns:

plot

Log-scaled plot on the x axis.

Other Parameters:
