The points in the graph look scattered, hence the plot is named as ‘Scatter plot’. Code Example. If you want nicely shaped spheres this means to draw many patches and thus gets slow quite quickly. ... (n, 0, 100) zs = randrange (n, zlow, zhigh) ax. Sign in to comment. How to increase marker size in scatter plot? Pour doubler la largeur (ou la hauteur) du marqueur, nous devons augmenter s par un facteur de 4 comme A=W*H => (2W)*(2H) = 4A. mplot3d import Axes3D from mpl_toolkits.
