We start with the simple one, only one line: 1. … Python and matplotlib recognize several dozen “named” colors. Using ax.spines [axes].set_color (‘color’), set the color of the axes. hue_order vector of strings. You have to to provide an amount of red, green, blue, and the transparency value to the color argument and it returns a color. matplotlib.lines.Line2D.

Iterate color and set color for all the lines. The matplotlib.colors.BoundaryNorm class is used to create a colormap based on discrete intervals. EXPLANATION: Like the vline () function, the matplotlib axvline () is also used to draw vertical lines across the plot’s axes. import matplotlib.pyplot...
