The object with the highest zorder is placed on top. To demonstrate, see the code below, where the scatter plot in the left subplot has zorder1 and in the right subplot it has zorder-1. # Defining the ratios for radius of pie chart markers r1 = 0.2 # 20% r2 = r1 + 0.2 # 40% r3 = r2 + 0.4 # 80% # define some sizes of the scatter marker sizes = np. You can manually choose in which order the different plots are to be displayed with the zorder parameter of e.g. The function returns a plot with desired axes and other parameters. With ‘none’, No patch boundary will be drawn. With ‘face’, the edge color will always be same as face color. ![]() edgecolors : or Color or Color Sequence – The edge color of the marker is set with this parameter.lindwidths : Float or array-like, default: 1.5 – The linewidth of marker is set using this parameter.alpha : Float, default: None – It’s a blending value where the range is between 0(transparent) and 1(opaque).vmin, vmax : Float, default: None – When norm is given these parameters aren’t used, but otherwise they help in mapping of color array c to colormap cmap.norm : Normalize, default: None – It helps in normalization of color data for the c.cmap : str or Colormap, default: ‘viridis’ – Used when we provide c an array of floats.import matplotlib.pyplot as plt import numpy as np Fixing random state for reproducibility np.ed(19680801) def randrange(n, vmin, vmax): ''' Helper function to make an array of random numbers having shape (n, ) with each number distributed Uniform (vmin, vmax). marker : MarkerStyle – For setting the marker style, this parameter comes handy Demonstration of a basic scatterplot in 3D.c : Array-like or List of Color or Color – This specifies the color of the marker.s : Float or array-like, shape(n,) – This parameter specifies the size of the marker.x,y : Float or array-like, shape(n,) – These are the two sets of values provided to the scatter function for plotting. ![]()
