Use Low-Level Functions for Speed

The features that make plotting functions easy to use also consume computer resources. If you want to maximize graphing performance, use low-level functions and disable certain automatic features.

Low-level graphics functions (e.g., line vs. plot, surface vs. surf) perform fewer operations and therefore are faster when you are creating many graphics objects.

The low-level graphics functions are line, patch, rectangle, surface, text, image, axes, and light
