Matplotlib markers in python have used mark points while line and scatter plots. 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. The center of the marker is located at (0, 0) and the size is normalized, such that the It accepts a scalar or an array. ), but now I wanna do it in 3D. random . twice bigger '+')? The s keyword argument controls the size of markers in plt.scatter(). If you want nicely shaped spheres this means to draw many patches and thus gets slow quite quickly. S = repmat([50,25,10],numel(X),1); C = repmat([1,2,3],numel(X),1); s = S(:); c = C(:); Create a 3-D scatter plot and use view to change the angle of the axes in the figure. By changing the color, size, and style of the markers, we can communicate more information and trends. c can be a scalar to uniformly change the marker color, or it can be an array to modify the marker color individually.
