There are a few methods given on this page (semilogx, semilogy, loglog) but they all do the same thing under the hood, which is to call set_xscale('log') (for x-axis) and set_yscale('log') (for y-axis).
1 Ιαν 2021 · How to Plot Logarithmic Axes in Matplotlib? Last Updated : 21 Jan, 2021. Axes’ in all plots using Matplotlib are linear by default, yscale () and xscale () method of the matplotlib.pyplot library can be used to change the y-axis or x-axis scale to logarithmic respectively.
The log scaling for Axes in 3D is an ongoing issue in matplotlib. Currently you can only relabel the axes with: ax.yaxis.set_scale('log') This will however not cause the axes to be scaled logarithmic but labeled logarithmic. ax.set_yscale('log') will cause an exception in 3D. See on github issue 209.
Axis scales# By default Matplotlib displays data on the axis using a linear scale. Matplotlib also supports logarithmic scales, and other less common scales as well. Usually this can be done directly by using the set_xscale or set_yscale methods.
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.
How to Plot Logarithmic Axes in Matplotlib is an essential skill for data visualization in Python. Logarithmic axes are particularly useful when dealing with data that spans several orders of magnitude or when you want to emphasize relative changes rather than absolute differences.
2 Φεβ 2024 · We can plot logarithmic axes in Matplotlibusing set_yscale(), semilogy() and loglog() functions.
