Conclusion: Matplotlib Marker. cmap: A map of colors to use in the plot. random . The marker color. Selon la documentation, s est la taille du marqueur en points**2. Pour faire un scatter plot en coordonnées logarithmiques : pyplot.xscale('log'): l'axe des x est en coordonnées logarithmiques (par défault avec facteur 10).Idem avec yscale pour l'axe des y. attention : si il y a des valeurs non représentables (par exemple valeurs à 0), indiquer le range à représenter : pyplot.xlim(1, 1000) par exemple. Markers can also be custom made depending on programmers choice. In the case of polar axis, the size of the marker increases radially, and also the color increases with an increase in angle.
