Due to the lack of a true 3D graphical rendering backend (such as OpenGL) and proper algorithm for detecting 3D objects' intersections, the 3D plotting capabilities of Matplotlib are not great but just adequate for typical applications. Let say we have to plot some graph in matplotlib which have x-axis and y-axis coordinate, let say x-axis extends from 0 to 10 and y. Plot data with y values that range between -15,000 and 15,000.
