A pixel is a square dot on the TI-84 Plus display. The
Pxl- (pixel) instructions let you turn
on, turn off, or reverse a pixel (dot) on the graph using the cursor. When you select a
pixel instruction from the
DRAW POINTS menu, the TI-84 Plus returns to the home screen
or the program editor. The pixel instructions are not interactive.
