One thing is important to note that the surface plot provides a relationship between two independent variables that are X and Z and a designated dependent variable that is Y, rather than just showing the individual data points. One is by using subplot() function and other by superimposition of second graph on the first i.e, all graphs will appear on the same plot. figure (). Matplotlib 3D Surface Plot - plot_surface() Function. How to create a Scatter Plot with several colors in Matplotlib? This creates a plot without a legend, using the default "viridis" colormap.
