Graphing a Discontinuous Function with PGFPLOTS (Unlocking LaTeX Graphics Episode 56)

In this episode of Unlocking LaTeX Graphics, applied mathematician Tammy Kolda demonstrates how to graph a discontinuous function using PGFPLOTS. Inspired by a Reddit discussion, she walks through creating a figure with axes in the middle, grid lines, open and closed circle marks, customized axes and grid lines; positioning title and axis labels; and adding TikZ nodes to a PGFPLOTS axis. Tammy also covers important details like document setup, setting compatibility level, and other styling options. Watch to enhance your LaTeX skills and recreate complex graphs using PGFPLOTS.
