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).
In this example, the distance between successive frequencies is 1 Hz, which is pretty good resolution. Also, symlog scaling is best. npts = int(sf) f, t, Sxx = signal.spectrogram(sig, sf, nperseg=npts) plt.yscale('symlog')
Learning how to plot logarithmic axes in Matplotlib is a valuable skill for data visualization. It allows you to effectively represent data that spans several orders of magnitude, highlight relative changes, and visualize exponential relationships.
1 Ιαν 2021 · Syntax: matplotlib.pyplot.yscale (value, **kwargs) Parameters: value = { “linear”, “log”, “symlog”, “logit”, …. **kwargs = Different keyword arguments are accepted, depending on the scale (matplotlib.scale.LinearScale, LogScale, SymmetricalLogScale, LogitScale) Returns : Converts the y-axes to the given scale type.
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.
11 Φεβ 2022 · Additionally, we will showcase how to plot figures with logarithmic axes using Python and matplotlib package and understand which method to use depending on whether you are using the Pyplot or Object-oriented interface.
This tutorial covered how to create plots with logarithmic axes using semilogy, semilogx, loglog, and errorbars plots. By using these types of plots, you can effectively visualize data that has a large range of values.
