These plots are represented in the matplotlib API by the semilogx() and semilogy() functions. The semi-log plots use linear scaling on one axis and logarithmic scaling on the other axis. It's the scale that changes, not the data. For whatever it's worth, data isn't filtered out, it's just a linear plot near 0 and a log plot everywhere else. The following code shows how to create a scatterplot using the variable z to color the markers based on category: import matplotlib. The log-log plot employs logarithmic scaling on both axes and is represented in matplotlib by the () function. For the zero-crossing behavior, what you're referring to is a 'Symmetric Log' plot (a.k.a. Suppose we have the following pandas DataFrame: import pandas as pdĭf = pd.DataFrame() Example 1: Color Scatterplot Points by Value This tutorial explains several examples of how to use this function in practice. You can use c to specify a variable to use for the color values and you can use cmap to specify the actual colors to use for the markers in the scatterplot.
